Question

Determine Which ratio forms a proportion with 7/2 by finding a common multiplier.

A- 35/8

B- 70/20

C- 28/10

D- 70/8

Answer 1

B will work very nicely. Just multiply 10/10 by 7/2 and you will get 70/20.

Answer 2

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

The ratio forms a proportion with $\frac{7}{2}$

By finding a common multiplier

A) $\frac{35}{8}$ can't be written as $\frac{7}{2}$

C) $\frac{28}{10}=\frac{14}{5}$ can't be written as $\frac{7}{2}$

D) $\frac{70}{8}=\frac{35}{4}$ can't be written as $\frac{7}{2}$

But,

B ) $\frac{70}{20}=\frac{7}{2}$ is correct .

Hence, Option 'B' is correct.
