Let’s solve each percentage problem step by step.
To find a percentage of a number, you multiply the number by the percentage (as a decimal).
For example: 52% of 210 = 0.52 × 210
We’ll go one by one:
---
1a. 52% of 210
→ 0.52 × 210 = 109.2
1b. 35% of 500
→ 0.35 × 500 = 175
---
2a. 56% of 838
→ 0.56 × 838 = let’s calculate:
0.56 × 800 = 448
0.56 × 38 = 21.28
Total = 448 + 21.28 =
469.28
2b. 88% of 915
→ 0.88 × 915
Break it down:
0.88 × 900 = 792
0.88 × 15 = 13.2
Total = 792 + 13.2 =
805.2
---
3a. 28% of 866
→ 0.28 × 866
0.28 × 800 = 224
0.28 × 66 = 18.48
Total = 224 + 18.48 =
242.48
3b. 69% of 49
→ 0.69 × 49
0.69 × 50 = 34.5 → subtract 0.69 → 34.5 - 0.69 =
33.81
---
4a. 50% of 780
→ Half of 780 =
390
4b. 85% of 994
→ 0.85 × 994
0.85 × 1000 = 850 → subtract 0.85 × 6 = 5.1 → 850 - 5.1 =
844.9
---
5a. 32% of 881
→ 0.32 × 881
0.32 × 800 = 256
0.32 × 81 = 25.92
Total = 256 + 25.92 =
281.92
5b. 39% of 719
→ 0.39 × 719
0.39 × 700 = 273
0.39 × 19 = 7.41
Total = 273 + 7.41 =
280.41
---
6a. 35% of 441
→ 0.35 × 441
0.35 × 400 = 140
0.35 × 41 = 14.35
Total = 140 + 14.35 =
154.35
6b. 67% of 429
→ 0.67 × 429
0.67 × 400 = 268
0.67 × 29 = 19.43
Total = 268 + 19.43 =
287.43
---
7a. 21% of 358
→ 0.21 × 358
0.21 × 300 = 63
0.21 × 58 = 12.18
Total = 63 + 12.18 =
75.18
7b. 47% of 6
→ 0.47 × 6 =
2.82
---
8a. 67% of 811
→ 0.67 × 811
0.67 × 800 = 536
0.67 × 11 = 7.37
Total = 536 + 7.37 =
543.37
8b. 97% of 311
→ 0.97 × 311
Think: 100% - 3% = 97%, so subtract 3% from 311
3% of 311 = 0.03 × 311 = 9.33
So 311 - 9.33 =
301.67
---
Final Answer:
1a. 109.2
1b. 175
2a. 469.28
2b. 805.2
3a. 242.48
3b. 33.81
4a. 390
4b. 844.9
5a. 281.92
5b. 280.41
6a. 154.35
6b. 287.43
7a. 75.18
7b. 2.82
8a. 543.37
8b. 301.67
