Millie, josh and liberty recieve a bonus at work they are paid in ratio of 2:3:4 josh's share is £105 what was the total amount of the bonus before they shared it?

I think you'd answer it like this;

£105 / 3 = 35.

So now we know 35 is the number that was multiplied.

You add the ratios, 2+3+4, which is 9.

35 x 9 = £315.

Millie gets 70

Josh gets 105

and that leaves 140 for Liberty.

The total amount of money before it was divided is : £315.
