Natasha and Richard win some money and share it in the ratio 3:5. Natasha gets £39. How much did they win in total?

104

Step-by-step explanation:

Natasha got 39, which is 3 parts of the total money. So you divide it by three.

39:3=13

13 corresponds to part of the total money. Richard gets 5 pieces, so you have to multiply the 13 by 5.

13*5=65

To find out how much money the two of them won together, you have to add up the shares.

13+65=104
