Find the missing number in each.
00:11 = 54 : 66
() 7: = 84 : 60
(ii) 10: 6 = 25:​

Answer 1

Answer:

1. 9:11 = 54:66
2. 7:5 = 84:60
3. 10:6 = 25:15

Step-by-step explanation:

1. x/11 = 54/66

x×66 = 54×11

x = (54×11)/66

x = 9

2. 7/x = 84/60

7×60 = 84×x

(7×60)/84 = x

x = 5

3. 10/6 = 25/x

10×x = 25×6

x = (25×6)/10

x = 15
