example:
in every month cora give 1,320.00 fo the monthly allowance of her children with a ratio of 4:3:5 find how many of each will receive?
this is a partitive proportion all you have to do is to add the given ratio.
4+3+5 = 12
divide to 1,320 .00
1,320 / 12 = 110
multiply 110 to the given ratio.
4* 110 = 440
3*110 = 330
5*110 =550
each of them will receive = 440.00, 330.00, 550.00
