$600 is shared among three boys in the ratio 3: 4: 5.
We find the total number of parts we want to divide our quantity just by adding the ratio quatities:
3 + 4 + 5 = 12
We divide:
$600 ÷ 12 = $50
We multiply by each ratio:
the smallest share will be:
3 x $50 = $150
The next will be:
4 x $50 = $200
The larger share will be:
5 x $50 = $250
