An objects weight on Mars is 38% of its weight on Earth. If an object weighs p, pounds on Earth, write an expression for its wei
oksano4ka [1.4K]

0.38p

To get the percent of something, you turn the percent to a decimal and multiply it to the number.

Here, we want the expression to get 38% of p. So we turn 38% to 0.38 and multiply it to p. Since we don't know what p is, we have to leave it as 0.38p

The answer is 0.38p


Hope this helps!
