Solve for the variable by using the Cross Products Property.
b = 10
To solve the proportion, we will start by using the Cross Products Property.
From here, we will continue solving for b by using the Division Property of Equality.
.LHS /5.=.RHS /5.
Cancel out common factors

Calculate quotient
Rearrange equation
b= 10
a/b=.a / 5./.b / 5.
Simplify quotient
Because both sides of the equation are the same, we know that our solution is correct!
