Answer 1

Step-by-step explanation:

(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.
