Amanda and Wim share some money in the ratio 2:5. Wim receives £115. Calculate how much money was shared?

First, you need to find value of one part. We can see that Wim who has a share of 5 parts gets £115. So, 5 parts is equivalent to £115. Therefore, value of each part is 115/5 = £23. Now, adding the ratios 2+5 gives you the total number of parts which is 7. Each part is worth £23, so total money is 7 x 23 = £161. You can check your answer is correct, by calculating Amanda's share of money which would be 2 (her share of parts) x 23 (value of each part)= £46. And check that Amanda's share of £46 plus Wim's share of £115 adds up to our total of £161.
