Exercise 1 Page 204

What number multiplied by 5 equals 20? Multiply 8 by that number.

d=32

Practice makes perfect
Let's pay close attention to the given proportion. 5/8 = 20/d

We need to find the number that we can multiply 5 by to get 20. 5* ? =20 We multiply 5 by 4 to get 20, so we will also multiply 8 by 4 to find the value of d.

8 * 4 = 32 = d

We see that d = 32.
