3. Write an equation and solve. Round to the nearest hundredth where necessary.

64 is 80% of what?

A 64. n=80; 0.8

B 0.64. n = 80; 125

C 80 = 64. n; 1.3

D 64 = 0.80 • n; 80

The answer is D. 64 =.80 * n; 80

Step-by-step explanation:

the word "is" in math means equal

the word "of" in math means multiply

So 64 is 80% of what? is saying 64 = 80%n

Let's turn 80% to a decimal, so that would equal 0.8

64 =.8n - -> I used n because n is "what"

now you solve for n. Divide both sides by. 8 and you get 80
