Step-by-step explanation:

Convert each fraction by setting up proportion out of 100.

$\frac{60}{90} = \frac{?}{100}$

$\frac{78}{150} = \frac{?}{100}$

$\frac{75}{120} = \frac{x}{100}$

Cross multiply each fraction. let x represent the missing number.

6000 = 90x

7800 = 150x

7500 = 120x

Solve for x

For the first equation.

x = 66.66666

For the second equation

x = 52

For the third equation,

x = 62.5

Round each missing value to the nearest whole value and add the % sign.

60/90=67%

78/150=52%

75/120=63%
