Answer:
30 £1 notes
and
10 £5 notes
Step-by-step explanation:
There is 3 times as many 1s than 5s.
If 5s is represented as x, and there are 3 times as many 1s than 5s, we can call the 1s 3x.
Now we put this in a ratio of 3x : x
By dividing both sides by x, the ratio becomes 3 : 1
3 add 1 is 4, so there are 4 parts in the ratio.
40 divided by 4 is 10, so each part of the ratio is worth 10
The ration is now 3 x 10 : 1 x 10
or
30 : 10
Therefore, there are:
30 £1 notes
and
10 £5 notes
