$330 has to be divided into three parts that are in the ratio 15:12:10.

Adding 15, 12 and 10 gives 15 + 12 + 10 = 37

The three parts are given by `330*15/37` , `330*12/37` and `330*10/37`

or 133.78, 107.02 and 89.18

Dividing $330 in three parts that are in the ratio 15:12:10 gives $133.78, $107.02 and $89.18

sharing $330 in 15:12:10 is dividing the money into (15+12+10) parts, then multiplying it by 15, 12 & 10.

Solution:

$330/(15+12+10)=8.92(corr to 3 sig. fig.)

8.92*15=133.8, 8.92*20=178.4, 8.92*10=89.2

The three shares are 133.8, 178.4 & 89.2 (corr to 3 sig. fig.).
