Scarlett and Aiden split $£63$ in the ratio $3:4$. We need to find how much money Aiden gets.

1. Problem Description

Scarlett and Aiden split $£63$ in the ratio $3:4$. We need to find how much money Aiden gets.

2. Solution Steps

First, we need to find the total number of parts in the ratio. This is the sum of the individual ratios.

Total parts = $3 + 4 = 7$

Now, we need to find the value of one part. We do this by dividing the total amount of money by the total number of parts.

Value of one part = $£63 / 7 = £9$

Since Aiden's share is 4 parts, we multiply the value of one part by 4 to find Aiden's share.

Aiden's share = $4 \times £9 = £36$

3. Final Answer

Aiden gets $£36$.
