Question

Enrique has to pay 80% of a $200 phone bill. Explain how to use equivalent ratios to find 80% of $200.

Answer 1

80/100*200=80*200/100=160 $

Answer 2

Sample Response: First, write 80% as 80/100. Then write an equivalent ratio that has the answer in the numerator and 200 in the denominator. 100 x 2 is 200, so 80 x 2 will be the answer. 80 x 2 = 160. The answer is $160
