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