To solve each problem, we use the basic percentage formula:
>
Percentage = (Part ÷ Whole) × 100%
In each question, “What percent of [Whole] is [Part]?” — so we divide the part by the whole and multiply by 100 to get the percentage.

Let’s solve each one step by step:
---
1. What percent of 70 is 24?
→ (24 ÷ 70) × 100
= 0.342857... × 100
≈
34.29%
*(Rounded to two decimal places)*
---
2. What percent of 30 is 21?
→ (21 ÷ 30) × 100
= 0.7 × 100
=
70%
---
3. What percent of 70 is 19?
→ (19 ÷ 70) × 100
= 0.271428... × 100
≈
27.14%
---
4. What percent of 50 is 18?
→ (18 ÷ 50) × 100
= 0.36 × 100
=
36%
---
5. What percent of 180 is 60?
→ (60 ÷ 180) × 100
= 0.333... × 100
=
33.33% *(or exactly 33⅓%)*
---
6. What percent of 10 is 2?
→ (2 ÷ 10) × 100
= 0.2 × 100
=
20%
---
7. What percent of 270 is 108?
→ (108 ÷ 270) × 100
= 0.4 × 100
=
40%
---
8. What percent of 80 is 42?
→ (42 ÷ 80) × 100
= 0.525 × 100
=
52.5%
---
9. What percent of 90 is 63?
→ (63 ÷ 90) × 100
= 0.7 × 100
=
70%
---
10. What percent of 120 is 36?
→ (36 ÷ 120) × 100
= 0.3 × 100
=
30%
