Final answer:
Paul originally had £40 before Dan gave him £32 to adjust the shares, making the ratio 1:1.
Step-by-step explanation:
Let's find out how much Paul originally had before Dan changed the ratio by giving him £32. The original ratio of Dan to Paul's share was 9:5. When Dan gives Paul £32, the share becomes equal, making the ratio 1:1.
Firstly, let's consider the difference in ratio parts between Dan and Paul, which is 9 - 5 = 4 parts. These 4 parts are equivalent to the £32 that Dan gave to Paul to equalize their shares.
Now, to find the value of 1 part, we would divide £32 by 4.
1 part = £32 / 4 = £8
Since Paul's original share was 5 parts, we would multiply 5 by £8 to find Paul's original amount.
Original amount Paul had = 5 parts * £8/part = £40
Therefore, Paul originally had £40 before Dan adjusted the shares to make the ratio equal.
