Exercise 84 Page 659

You can solve for the variable by using the Properties of Equality.

86.5

Practice makes perfect

To solve the proportion, we will start by using the Properties of Equality in order to isolate the variable.

0.37=32/x

LHS * x=RHS* x

0.37 * x=32

.LHS /0.37.=.RHS /0.37.

x=32/0.37

Now, let's simplify the obtained expression and round it to the nearest tenth if necessary.

x=32/0.37

a/b=a * 100/b * 100

x=3200/37

Calculate quotient

x=86.48648...

Round to 1 decimal place(s)

x≈ 86.5
