Question

20. (a) Write 8% as a decimal number.

(43)
(b) Find 8% of $8.90 by multiplying $8.90 by the answer
to part (a). Round the answer to the nearest cent.

Answer 1

(a) = 0.08

(b) = $0.71

Explanation:

(a) We can determine the decimal form of 8% two ways.

(1) We can rewrite 8% as 8/100 since a percent is always out of 100. When you divide 8 by 100, you get 0.08.

(2) Or we can rewrite 8% as 8.00%. Then, we can move the decimal two places to the left (same as dividing by 100) and drop the percent symbol which gives us 0.08.

(b) 0.08 * 8.90 = 0.712. Rounding to the nearest cent gives us $0.71
