I need help
Solve for a
a+b=c

Step-by-step explanation:

What is it that you need help with exactly?

A+B=C

It's already been solved. Do you need it in a different form?

(a/(b/c)

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.
