Question

Divide 1 hour in the ratio 1 : 9 : 10

3 minutes; 27 minutes; 30 minutes

 
0.05 minutes; 0.45 minutes; 0.5 minutes

 
30 minutes; 27 minutes; 3 minutes​

Answer 1

3 minutes; 27 minutes; 30 minutes

Explanation:

Let the common multiplier of the given ratios be x. So, the ratios 1: 9 : 10 will become x, 9x and 10x respectively.

Therefore,

`x + 9x + 10x = 1 \: hour \\ \\ 20x = 60 \: minutes \\ \\ x = (60 \: minutes)/(3) \\ \\ x = 3 \: minutes \\ \\ 9x = 9 * 3 = 27 \: minutes \\ \\ 10x = 10 * 3 = 30 \: minutes`

Thus, 1 hour in the ratio 1 : 9 : 10 can be divided as:

3 minutes; 27 minutes; 30 minutes
