Question

Please help

Colin , Dave and Emma share some money
Colin gets 3/10 of the money
Emma and Dave share the rest of the money in the ratio 3 : 2
what is Dave's share of the money ?

Answer 1

Between emma and dave, we have 7/10ths of the money

3x + 2x = 7/10

5x = 7/10

x=(7/10)/5

x= 14/100

Dave will get 28/100 or 7/25ths

Check : 30/100 Colin
42/100 Emma
+ 28/100 Dave
-----------
100/00
