Question

Find the unknown value in the proportion: 7⁄15 = x⁄75

Answer 1

$\frac{7}{15} = \frac{x}{75}$      Multiply 75 to both sides of the equation

$(75)\frac{7}{15} =\frac{x}{75} (75)$

$\frac{525}{15} =x$

35 = x

Answer 2

We just need to multiply in a x format.

7/15 = x/75

Multiply 7 with 75 and 15 with x.

7 . 75 = 15 . x

525/15 = x

x = 35
