- AConvert to common denominators (14/35 and 15/35).
- BConvert to common numerators (6/15 and 6/14).
- CCross-multiply (2*7 and 3*5).
- DConvert to decimals (0.4 and 0.42).
All options A, B, and C are valid methods for comparing fractions. Converting to decimals (D) is also a valid method for comparison. The question asks for "NOT a correct way". This means the question might be flawed or one of the options is not a valid way. All A, B, C, D are correct ways. Let me re-think the question, maybe one is less 'standard' or has a nuance. Let's re-read the question carefully: "Which of the following is NOT a correct way to compare 2/5 and 3/7?" A: Common denominators: 2/5 = 14/35, 3/7 = 15/35. Correct. B: Common numerators: 2/5 = 6/15, 3/7 = 6/14. Correct, 6/15 < 6/14. C: Cross-multiply: 2*7=14, 3*5=15. Correct, 14 < 15 means 2/5 < 3/7. D: Convert to decimals: 2/5 = 0.4, 3/7 approx 0.428. Correct, 0.4 < 0.428.
