(a) Anne, Barry and Colin share a prize in the ratio 3:4:5.
Colin gives 1/3 of his share to a charity.
What fraction of the whole prize does Colin give to the charity

Respuesta :

Answer: 1/12

Step-by-step explanation:

1. Add up the 3 parts making 12

3:4:5 = 3+4+5=12

2. Out of the ratio we know that Colin gets 5 parts which is 5/12

3. If we subtract 5/12 from 1/3 we should get an answer of 1/12

5/12-1/3 =1/12
