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.

Explanation:

Since we have given that

The ratio forms a proportion with
`(7)/(2)`

By finding a common multiplier

A)
`(35)/(8)` can't be written as
`(7)/(2)`

C)
`(28)/(10)=(14)/(5)` can't be written as
`(7)/(2)`

D)
`(70)/(8)=(35)/(4)` can't be written as
`(7)/(2)`

But,

B )
`(70)/(20)=(7)/(2)` is correct .

Hence, Option 'B' is correct.
