Answers
Answer:
Find each of the following ratios in the simplest form:
(i) 24 to 56
(ii) 84 paise to Rs 3
(iii) 4 kg to 750 g
(iv) 1.8 kg to 6 kg
(v) 48 minutes to 1 hour
(vi) 2.4 km to 900 m
ANSWER:
(i) 24:56 = 24 = 24 ÷ 8 = 3
56 56 ÷ 8 7
As the H.C.F. of 3 and 7 is 1, the simplest form of 24:56 is 3:7.
(ii) 84 paise to Rs 3 = Rs 0.84 to R. 3 = 0.84 = 0.84 ÷ 3 = 0.28 = 28 = 28 ÷ 4 = 7
3 3 ÷ 3 1 100 100 ÷ 4 25
As the H.C.F. of 7 and 25 is 1, the simplest form of 0.84:3 is 7:25.
(iii) 4 kg:750 g = 4000 g:750 g = 4000 ÷ 250 = 16
750 ÷ 250 3
As the H.C.F. of 16 and 3 is 1, the simplest form of 4000:750 is 16:3.
(iv) 1.8 kg:6 kg = 1.8 = 18 = 18 ÷ 6 = 3
6 60 60 ÷ 6 10
As the H.C.F. of 3 and 10 is 1, the simplest form of 1.8:6 is 3:1.
