Answer:
♦ 80 is what percent of 400?
a. Base
b. Rate
c. Percentage
Answer: b. Rate
Solution:-
- 80 = x% of 400
- x% × 400 = 80
- x/100 × 400 = 80
- 4x = 80
- x = 80/4
- x = 20
80 is 20% of 400 ( the rate is the percent)
♦ 16% of what number is 56?
a. Base
b. Rate
c. Percentage
Answer: a. Base
Solution:-
- 16% of x = 56
- 16/100 × x = 56
- 16x/100 = 56
- 16x = 56 × 100
- x = 5600/16
- x = 350
16% of 350 is 56 (The base is the amount which you're taking a percent of)
