Caroline and sarah win some money and share it in the ratio 4: 1. caroline gets £48. how much did they win in total?

48/3=12
12x5=60
so they one £60 total

Lets get started :)

Caroline : Sarah
        4     :     1                                   4r + 1r = ?
       48   :      x

4r = 48 ( Caroline's ratio )
Because she got £48 after the ratio division between the two

r = 12

= 4r + 1r
= 4 ( 12 ) + 1 ( 12 )
= 48 + 12
= 60

They won £60 in total
