Step-by-step explanation:
Write each of the following ratios in the simplest form:
(i) Rs 6.30 : Rs 16.80
(ii) 3 weeks : 30 days
(iii) 3 m 5 cm : 35 cm
(iv) 48 min : 2 hours 40 min
(v) 1 L 35 mL : 270 mL
(vi) 4 kg : 2 kg 500 g
ANSWER:
(i) Rs 6.30:Rs 16.80
6.30 = 63 = 63 ÷ 21 = 3 (H.C.F. of 63 and 168 is 21.)
16.80 168 168 ÷ 21 8
Ratio = 3 : 8
(ii)3 weeks:30 days = 21days:30 days (1 week = 7 days)
21 = 21 ÷ 3 = 7 (H.C.F. of 21 and 30 is 3.)
30 30 ÷ 3 10
Ratio = 7 : 10
(iii) 3 m 5 cm:35 cm = 305 cm:35 cm (1 m = 100 cm)
305 = 305 ÷ 5 = 61 (H.C.F. of 305 and 35 is 5.)
35 35 ÷ 5 7
Ratio = 61:7
(iv) 48 min:2 hours 40 min = 48 min:160 min (1 hour = 60 mins)
48 = 48 ÷ 16 = 3 (H.C.F. of 48 and 160 is 16.)
160 160 ÷ 16 10
Ratio = 3:10
(v) 1 L 35 mL:270 mL = 1035 mL:270 mL (1 L = 1000 mL)
1035 = 1035 ÷ 45 = 23 (H.C.F. of 1035 and 270 is 45.)
270 270 ÷ 45 6
Ratio = 23:6
(vi) 4 kg:2 kg 500 g = 4000 g:2500 g (1 kg= 1000 g)
4000 = 40 = 40 ÷ 5 = 8 (H.C.F. of 40 and 25 is 5.)
2500 25 25 ÷ 5 5
Ratio = 8:5
