In the given circle, values of AP, CP and DP are 12m, 6m and 5m respectively .
Substituting the values in the formula, we will get

Dividing both sides by 5

6:$9
Multiply both by 2 (because 12/6=2)
And get 12:$18
3:7
Multiply both by 2 (because 14/7=2)
And get 6:14
6:3
Multiply both by 8 (48/6=8)
And get 48:24
