Divide 132kg in a ratio of 3:3:5

In this case, we will want to divide the original amount by the sum of the integers in ratio: (3+3+5), that is by 11. 132 divided by 11 is 12.

So twelve will be our "unit" here and the numbers 3,3 and 5 will refer to the multiples of this unit:

3*12=36

3*12=36

5*12=60

So the answer is:

36:36:60.

now, let's check if it add up t0 132? 36+36+60 = 132, correct.
