Based on the problem above, the given values are as follows: 2:3:4 = Ratio of Millie, Josh and Libby's bonus £105=Josh's share of the bonus ?=total amount of the bonus they shared. In order to get this, we need to solve for Millie's and Libby's bonuses. So to get Millie's share: we do this. 2/3 : x/105. Cross multiply and divide and we get x=70. Therefore, Millie's share is £70. Next is Libby's: 3/4 : 105/y. Cross multiply and divide and we get y=140. Therefore, Libby's share is £140. Now, add up everything and we get £315. So the total amount of the bonus before they shared it is £315.
