QUESTION 16

What is the value of m If the ratios 3:18 and m:42 are in

proportion?

Answer 1

`m = 7`

Explanation:

Given

`3:18 = m:42`

Required

Solve for m

`3:18 = m:42`

Convert to fraction

`(3)/(18) = (m)/(42)`

Multiply both sides by 42

`42 * (3)/(18) = (m)/(42) * 42`

`42 * (3)/(18) = m`

`m = 42 * (3)/(18)`

`m = (42 * 3)/(18)`

`m = (126)/(18)`

`m = 7`
