Question

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

Answer 1

For some number $x$, the number 132 can be divided into $3x$, $3x$, and $5x$.

The sum of the three numbers is
$3x+3x+5x=132$

Solve for $x$:
$3x+3x+5x=132$
$\rightarrow11x=132$
$\rightarrow x=12$

Plug into $3x$ and $5x$:
$3x=3*12=36$
$5x=5*12=60$

So the division comes out as 36 kg, 36 kg, 60 kg.

Answer 2

Add the ratios together and divide them by 132. then times the number by the answer you get.

3+3+5=11

132÷11=12

12×3=36

12×3=36

12×5=60

so: 36:36:60
