the question says "Divide £50 into the ratio 2:3"
2:3 means that we divide £50 into two bits where one bit is 3/2 times the other.
Thus let the bits be a and 50-a, as they have to add up to £50 altogether.
Thus 50-a = (3/2)a, so add a to both sides to give (5/2)a = 50 -> multiply by 2/5 to give a = 20. Thus the other bit is 50-20 = 30, so we have that £50 divided in the ratio 2:3 is £20 and £30.

You know the ratio 2:3 is also a fractional notation which may be easier to understand.
The denominator of each fraction = the sum of the numbers in the ratio (2+3) =5
Therefore the fractions would be = 2/5 and 3/5
To get the answer you simply times 50 by these two fractions respectively.
I believe you would then get: 20 and 30 as your answer.
Fingers crossed this helped you m8
