Answer:
(i)
72 : 60 =
72
60
=72÷12
60÷12
=65
= 6 : 5 (HCF of 72 and 60 = 12)
Thus, the reduced form of 72 : 60 is 6 : 5.
(ii)
38 : 57 =
38
57
=38÷19
57÷19
=23
= 2 : 3 (HCF of 38 and 57 = 19)
Thus, the reduced form of 38 : 57 is 2 : 3.
(iii)
52 : 78 = 52
78
=52÷26
78÷26
=23
= 2 : 3 (HCF of 52 and 78 = 26)
Thus, the reduced form of 52 : 78 is 2 : 3.
