Translate the following expression to an equation in terms of p: "151.8 is what percent of 69?"

Lostsunrise [7]

The statement "151.8 is what percent of 69 is expressed as 0.69p = 151.8

<h3>Equations and expressions</h3>

Equations are expressions separated by an equal sign. Words can be translated to equations.

Let the unknown variable be "p". If p percent of 69is 151.8, this is expressed as;

p% of 69 = 151.8

Convert to decimals

p/100 * 69 = 151.8

0.01p * 69 = 151.8
0.69p = 151.8

Hence the statement "151.8 is what percent of 69 is expressed as 0.69p = 151.8
