Question

Three of these fractions are equivalent A.30/70 B.12/30 C.9/21 D.6/14 which one is the odd one out

Answer 1

Step-by-step explanation:

30/70 (divide by 10) is 3/7

12/30 (divide by 6) is 2/5

9/21 (divide by 3) is 3/7

6/14 (divide by 2) is 3/7

Hence 30/70, 9/21 and 6/14 are equivalent fractions

Therefore, the fraction 12/30 is the odd one out

Answer 2

Answer:

B.12/30

Step-by-step explanation:

$\frac{30}{70} =\frac{30:10}{70:10} =\frac{3}{7}\\\\\frac{9}{21} =\frac{9:3}{21:3} =\frac{3}{7}\\\\\frac{6}{14} =\frac{6:2}{14:2} =\frac{3}{7}$
