Answer 1

57.10
70.9
these are only the answers for the first two problems

Answer 2

1) Convert fraction into a decimal: 4 / 7 = 0.5714... Round to nearest tenth. The 5 is in the tenth place. Look at the digit on the right of 5. Is it equal or greater than 5? Yes. 7 is greater than 5. We round up to 0.60. Convert decimal to percent: 0.60 => 60%

2) Just move the decimal point two places to the right: 0.709 => 70.9%

3) We know that 1/3 is equal to 33 1/3%. Just multiply 33 1/3% by two.

0.333... * 2 = 0.6666... = 66 2/3%

4) Alice gets 21 free throws and makes 81.25% of them. The question then asks "how many free throws she makes". Well just multiply 81.25% by 21:
0.8125 * 21 ≈ 17

5) Convert percent into decimal: 48% => 0.48
Multiply: 0.48 * 23.95 ≈ $11.50

6) Multiply 15% by 58.50: 0.15 * 58.50 ≈ $8.80
