You can solve the proportion by using the Cross Products Property.

15/8

Practice makes perfect

To solve the proportion, let's start by using the Cross Products Property, then we will apply the Division Property of Equality.

5/8=y/3

Cross multiply

5(3)=8y

Multiply

15=8y

.LHS /8.=.RHS /8.

15/8=y

Rearrange equation

y=15/8

Therefore, the solution for the given equation is y= 158.
