Answer key · Interpret data presented in circle graphs

1.
6 — 15% of 40 = 40 × 15 ÷ 100 = 6.
2.
6 — 10% of 60 = 60 × 10 ÷ 100 = 6.
3.
27 — 45% of 60 = 60 × 45 ÷ 100 = 27.
4.
25 — 25 out of 100 = 25 ÷ 100 × 100 = 25%.
5.
25 — 10 out of 40 = 10 ÷ 40 × 100 = 25%.
6.
60 — 60 out of 100 = 60 ÷ 100 × 100 = 60%.
7.
24 — The rest is 40% of 60 = 24 people.
8.
36 — The rest is 45% of 80 = 36 people.
9.
36 — The rest is 60% of 60 = 36 people.
