Writing it out like this will help:

7 : 3 : 2

? : 3.75 : ?

So, 3.75 is 3 parts as per this ratio

Divide this amount by 3 to get 1 part in the ratio

3.75 / 3 = 1.25

Now simply multiply all the other ratios by this value to find how much the others get:

1.25 x 7 = 8.75

1.25 x 2 = 2.5

Paula gets £8.75 and Henry gets £2.50

The amount altogether would be their individual amounts added together:

8.75 + 2.50 + 3.75 = 15

The total amount of money is £15.

Hope This Helps You!

Good Luck (:

Have A Great Day ^-^
