Exercise 1 Page 58

Solve for the variable by using the Cross Products Property.

k=4

Practice makes perfect

To solve the proportion, we will start by using the Cross Products Property.

k/7 = 32/56

Cross multiply

k * 56 = 7 * 32

Multiply

56k = 224

From here, we will continue solving for k by using the Division Property of Equality.

56k = 224

Distribute 56

k = 224/56

Use a calculator

k = 4

Checking Our Answer

Let's Check!

Now we can check our answer by substituting it into the original equation.

k/7 = 32/56

k= 4

4/7? =32/56

a/b=.a / 8./.b / 8.

4/7? =32/ 8/56/ 8

Simplify quotient

4/7 = 4/7 ✓

Because both sides of the equation are the same, we know that our solution is correct!
