Help asap please im failing

Step-by-step explanation:
Convert each fraction by setting up proportion out of 100.
[tex] \frac{60}{90} = \frac{?}{100} [/tex]
[tex] \frac{78}{150} = \frac{?}{100} [/tex]
[tex] \frac{75}{120} = \frac{x}{100} [/tex]
Cross multiply each fraction. let x represent the missing number.
[tex]6000 = 90x[/tex]
[tex]7800 = 150x[/tex]
[tex]7500 = 120x[/tex]
Solve for x
For the first equation.
[tex]x = 66.66666[/tex]
For the second equation
[tex]x = 52[/tex]
For the third equation,
[tex]x = 62.5[/tex]
Round each missing value to the nearest whole value and add the % sign.
60/90=67%
78/150=52%
75/120=63%
