Answer key · Interpret data presented in circle graphs

1.
12 — 15% of 80 = 80 × 15 ÷ 100 = 12.
2.
20 — 25% of 80 = 80 × 25 ÷ 100 = 20.
3.
4 — 10% of 40 = 40 × 10 ÷ 100 = 4.
4.
55 — 33 out of 60 = 33 ÷ 60 × 100 = 55%.
5.
40 — 40 out of 100 = 40 ÷ 100 × 100 = 40%.
6.
30 — 30 out of 100 = 30 ÷ 100 × 100 = 30%.
7.
33 — The rest is 55% of 60 = 33 people.
8.
26 — The rest is 65% of 40 = 26 people.
9.
36 — The rest is 45% of 80 = 36 people.
