(iii) 17 of 51?
What percentage is:
(i) 30 min of 4 h?
(ii) 500 g of 3 kg?
(iii) 3 months of 3 year?

Answer 1

Step-by-step explanation:

1. 6.25%
2. 11.11^%
3. 33.33^%

1. 1 hour = 60 minutes

4 hour= 60x40

= 2400

therefore,

30 ÷ 2400x100

1.25%

2. 1 kg = 1000 gm

3 kg = 3000 gm

therefore, 500 ÷ 3000 x 100

= 16.66^%

3. 1 year = 12 month

3 year = 3x12

= 36

therefore,

3 ÷ 36 x 100

8.33^%
