Exercise 5 Page 504

Solve for the variable by using the Cross Products Property.

2

Practice makes perfect

To solve the proportion, we will use the Cross Products Property.

n/5 = 18/45

Cross multiply

45n = 5(18)

.LHS /45.=.RHS /45.

45n/45 = 5(18)/45

CancelCommonFac

Cancel out common factors

45n/45 = 5(18)/45

Simplify quotient

n = 5(18)/45

Multiply

n = 90/45

Calculate quotient

n = 2
