(a) 40 persons : 200 persons = 40/200 =1/5 = 1 : 5 Rs.15 : Rs.75 = 15/75 = 1/5 = 1 : 5
Since, 40 persons : 200 persons = Rs.15 : Rs.75
Hence, the statement is true.
(b) 7.5 liters : 15 liters = 7.5/15 = 75/150 = 1/2 = 1 : 2
5 kg : 10 kg = 5/10 = 1/2 = 1 : 2
Since, 7.5 liters : 15 liters = 5 kg : 10 kg
Hence, the statement is true.
(c) 99 kg : 45 kg = 99/45 = 11/5 = 11 : 5
Rs.44 : Rs.20 = 44/20 =11/5 = 11 : 5
Since, 99 kg : 45 kg = Rs.44 : Rs.20
Hence, the statement is true.
(d) 32 m : 64 m = 32/64 = 1/2 = 1 : 2
6 sec : 12 sec = 6 /12 = 1 /2 = 1 : 2
Since, 32 m : 64 m = 6 sec : 12 sec
Hence, the statement is true.
(e) 45 km : 60 km = 45 /60 =3/4 = 3 : 4
12 hours : 15 hours = 12/15 = 4/5 = 4 : 5
Since, 45 km : 60 km ¹ 12 hours : 15 hours
Hence, the statement is true
