Q1.If 3/5 of the students in a class are boys, and there are 20 girls, what is the total number of students in the class?
A.30
B.40
C.50
D.60
Answer: 50

If 3/5 are boys, then 1 - 3/5 = 2/5 of the students are girls. If 2/5 of the students equals 20 girls, then 1/5 of the students is 10. So, the total number of students (5/5) is 5 * 10 = 50.

Q2.Which of the following is an improper fraction?
A.7/8
B.12/11
C.3/4
D.5/6
Answer: 12/11

An improper fraction is a fraction where the numerator is greater than or equal to the denominator. In 12/11, 12 is greater than 11.

Q3.A marathon runner completed 3/10 of the race in the first hour and 2/5 in the second hour. If the total distance is 40 km, how many kilometers did he run in the first two hours?
A.12 km
B.16 km
C.28 km
D.32 km
Answer: 28 km

Fraction of race completed = 3/10 + 2/5 = 3/10 + 4/10 = 7/10. Distance run = (7/10) * 40 km = 7 * 4 = 28 km.

Q4.A rope is 5 meters long. If you cut 2 1/4 meters from it, what fraction of the original rope is left?
A.2 3/4 meters
B.11/20
C.9/20
D.2 1/4 meters
Answer: 11/20

Amount left = 5 - 2 1/4 = 5 - 9/4 = 20/4 - 9/4 = 11/4 meters. As a fraction of the original rope, it's (11/4) / 5 = 11/4 * 1/5 = 11/20.

Q5.Let's re-write the question with this modification. A baker used 3/4 kg of flour for cakes and 1/8 kg for cookies. If he started with 1 3/4 kg of flour, how much flour is left?
A.5/8 kg
B.1 kg
C.7/8 kg
D.1 1/4 kg
Answer: 7/8 kg

Total flour used = 3/4 + 1/8 = 6/8 + 1/8 = 7/8 kg. He started with 1 3/4 kg = 7/4 kg = 14/8 kg. Flour left = 14/8 - 7/8 = 7/8 kg.

Q6.Which of the following fractions is NOT in its simplest form?
A.13/26
B.7/11
C.5/9
D.17/23
Answer: 13/26

The fraction 13/26 can be simplified by dividing both numerator and denominator by their greatest common factor, which is 13. This simplifies to 1/2.

Q7.Which of the following fractions is equivalent to 3/4 and has a denominator of 28?
A.18/28
B.21/28
C.24/28
D.15/28
Answer: 21/28

To change the denominator from 4 to 28, you multiply by 7. So, multiply the numerator by 7 as well: 3 * 7 = 21. The equivalent fraction is 21/28.

Q8.Let's use the correct option for C. In a school election, 2/5 of the votes went to Candidate A, 1/4 to Candidate B, and the rest to Candidate C. What fraction of the votes did Candidate C receive?
A.3/20
B.7/20
C.9/20
D.11/20
Answer: 7/20

Total votes for Candidate A and B = 2/5 + 1/4 = 8/20 + 5/20 = 13/20. The rest for Candidate C = 1 - 13/20 = 7/20.

Q9.Which fraction is an improper fraction that is equivalent to 3 2/5?
A.13/5
B.17/5
C.10/5
D.8/5
Answer: 17/5

To convert a mixed fraction to an improper fraction, multiply the whole number by the denominator and add the numerator: (3 * 5) + 2 = 15 + 2 = 17. Keep the same denominator: 17/5.

Q10.The product of two fractions is 5/12. If one fraction is 1/3, what is the other fraction?
A.5/4
B.5/36
C.4/5
D.3/4
Answer: 5/4

Let the other fraction be x. Then (1/3) * x = 5/12. To find x, divide 5/12 by 1/3: x = (5/12) ÷ (1/3) = 5/12 * 3/1 = 15/12 = 5/4.

Q11.A water tank is 3/4 full. If 1/3 of the water is drained out, what fraction of the tank is still full?
A.1/4
B.1/2
C.2/3
D.5/12
Answer: 1/2

If 1/3 of the water is drained, then 1 - 1/3 = 2/3 of the current water remains. Remaining water = (2/3) * (3/4) = 6/12 = 1/2 of the tank.

Q12.What is the value of 1 1/3 * 2 1/4?
A.3
B.2 1/12
C.3 1/3
D.2 1/2
Answer: 3

Convert to improper fractions: 1 1/3 = 4/3, 2 1/4 = 9/4. Multiply: (4/3) * (9/4) = (4*9) / (3*4) = 36/12 = 3.

Q13.A recipe calls for 1/2 cup of sugar and 3/4 cup of flour. If you double the recipe, how much total sugar and flour do you need?
A.1 1/4 cups
B.2 1/2 cups
C.1 3/4 cups
D.2 cups
Answer: 2 1/2 cups

Total ingredients for original recipe = 1/2 + 3/4 = 2/4 + 3/4 = 5/4 cups. Doubling the recipe means 2 * (5/4) = 10/4 = 5/2 = 2 1/2 cups.

Q14.Which fraction, when placed in the blank, makes the statement 1/3 + _____ = 5/6 true?
A.1/2
B.2/3
C.1/6
D.5/6
Answer: 1/2

Subtract 1/3 from 5/6: 5/6 - 1/3 = 5/6 - 2/6 = 3/6 = 1/2.

Q15.A school day is 6 hours long. If 1/4 of the day is spent on Mathematics and 1/3 on Science, how many hours are left for other subjects?
A.1 hour
B.2 hours
C.2.5 hours
D.3.5 hours
Answer: 2.5 hours

Time for Maths = (1/4) * 6 = 1.5 hours. Time for Science = (1/3) * 6 = 2 hours. Total time for Maths and Science = 1.5 + 2 = 3.5 hours. Time left = 6 - 3.5 = 2.5 hours.

Q16.What is the value of 1/2 + 1/3 + 1/6?
A.5/6
B.2/3
C.1
D.1 1/6
Answer: 1

Find a common denominator, which is 6. 1/2 = 3/6, 1/3 = 2/6. Sum = 3/6 + 2/6 + 1/6 = 6/6 = 1.

Q17.If you divide 2 by 1/4, what is the result?
A.1/8
B.8
C.1/2
D.2
Answer: 8

Dividing by a fraction is the same as multiplying by its reciprocal: 2 ÷ (1/4) = 2 * (4/1) = 8.

Q18.Rina cut a cake into 12 equal slices. She ate 3 slices and gave 4 slices to her friends. What fraction of the cake is left?
A.5/12
B.7/12
C.1/3
D.1/4
Answer: 5/12

Total slices eaten or given away = 3 + 4 = 7 slices. Remaining slices = 12 - 7 = 5 slices. So, the fraction left is 5/12.

Q19.When comparing 4/5, 7/10, and 3/4, which fraction is the smallest?
A.4/5
B.7/10
C.3/4
D.They are all equal.
Answer: 7/10

To compare, find a common denominator, which is 20. 4/5 = 16/20, 7/10 = 14/20, and 3/4 = 15/20. The smallest is 14/20, which is 7/10.

Q20.A bottle contains 3/5 litres of juice. If Rohan drinks 1/2 of the juice, how much juice is left in the bottle?
A.1/5 litre
B.3/10 litre
C.1/2 litre
D.2/5 litre
Answer: 3/10 litre

Rohan drinks 1/2 of the 3/5 litres, which is (1/2) * (3/5) = 3/10 litres. The amount left is 3/5 - 3/10 = 6/10 - 3/10 = 3/10 litres.

Q21.Which statement is true about mixed fractions?
A.They are always less than 1.
B.They represent a sum of a whole number and an improper fraction.
C.They can be converted into improper fractions.
D.They have a numerator smaller than the denominator.
Answer: They can be converted into improper fractions.

A mixed fraction consists of a whole number and a proper fraction and can always be converted into an improper fraction by multiplying the whole number by the denominator and adding the numerator, then placing it over the original denominator.

Q22.A farmer divided his field into 4 equal parts. He planted wheat in 1 part, maize in 2 parts. What fraction of the field is left unplanted?
A.1/4
B.1/2
C.3/4
D.1/3
Answer: 1/4

Fraction planted = 1/4 (wheat) + 2/4 (maize) = 3/4. Fraction unplanted = 1 - 3/4 = 1/4.

Q23.Which of these expressions gives the smallest value?
A.1/2 + 1/4
B.3/4 - 1/8
C.1/5 + 3/10
D.1 - 2/3
Answer: 1 - 2/3

Calculate each: A) 1/2 + 1/4 = 2/4 + 1/4 = 3/4. B) 3/4 - 1/8 = 6/8 - 1/8 = 5/8. C) 1/5 + 3/10 = 2/10 + 3/10 = 5/10 = 1/2. D) 1 - 2/3 = 1/3. Comparing 3/4 (0.75), 5/8 (0.625), 1/2 (0.5), 1/3 (0.33...). The smallest is 1/3.

Q24.What is the reciprocal of 5 1/2?
A.2/11
B.11/2
C.5/2
D.1/5.5
Answer: 2/11

First, convert 5 1/2 to an improper fraction: 11/2. The reciprocal of 11/2 is 2/11.

Q25.In a bag, there are red, blue, and green marbles. 1/2 are red, and 1/4 are blue. What fraction of the marbles are green?
A.1/4
B.1/2
C.3/4
D.1/8
Answer: 1/4

Total fraction of red and blue marbles = 1/2 + 1/4 = 2/4 + 1/4 = 3/4. Fraction of green marbles = 1 - 3/4 = 1/4.

Q26.If a car's fuel tank is 7/10 full and consumes 1/5 of its capacity, what fraction of the tank is still full?
A.1/2
B.6/10
C.3/5
D.1/10
Answer: 1/2

Fraction of tank consumed = 1/5. Fraction remaining = 7/10 - 1/5 = 7/10 - 2/10 = 5/10 = 1/2.

Q27.Which fraction is halfway between 1/4 and 3/4?
A.1/2
B.5/8
C.3/8
D.1/3
Answer: 1/2

To find the fraction halfway between two numbers, add them and divide by 2: (1/4 + 3/4) / 2 = (4/4) / 2 = 1 / 2 = 1/2.

Q28.Which of the following is equivalent to 1?
A.3/3
B.0/5
C.1/0
D.5/1
Answer: 3/3

A.1/2
B.1/4
C.1/8
D.5/8

A.5
B.25
C.6
D.15
Answer: 25

To find 5/6 of 30, multiply the fraction by the whole number: (5/6) * 30 = (5 * 30) / 6 = 150 / 6 = 25.
