Exercise 23 Page 547

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

3

Practice makes perfect

To solve the proportion, we will start by simplifying the quotients, then we will use the Cross Products Property.

4x/24=56/112

a/b=.a /4./.b /4.

x/6=56/112

a/b=.a /56./.b /56.

x/6=1/2

Cross multiply

2x=6

.LHS /2.=.RHS /2.

x=3

Therefore, the solution for the given equation is x=3.
