b. 18% of 457 kg

h. 1% of 5
c. 13% of 325 cm
f. 5% of 2 km
i. 33 1/2% of 1200 kg
​

Answer 1

1. 25% of 300 = 25/100 × 300=75
2. 29.5% of 850m = 29.5/100 × 850 = 250.75 m
3. 75% of 2 days or 75% of 48hrs = 75/100 × 48 = 36hrs
4. 18% of 457kg = 18/100 ×457 = 82.26kg
5. 50% of 1 hr = 50/100 ×1 = 1/2hrs or 30minutes
6. 1% of 5 = 1/100 × 5 = 1/20 or 0.05
7. 13% of 325cm = 42.25cm
8. 5% of 2km = 5/100 × 2 = 1/10km or 100m
9. 33 1/2 % of 1200 kg = 67/2% of 1200kg =

67/(2×100) × 1200 = 67/200 × 1200 = 67 × 6

402kg
