Using a multiplier, find 85% of £30

Svetradugi [14.3K]

Answer:

£25.50

Step-by-step explanation:

I don't know what you mean by multiplier but to find 85% of £30 you do:

10% of 30 which is 3

80% is 24

5% is 1.5 (to find 5% you find 10% then divide by 2)

Now add 24 and 1.5. Do not add the 10% becuase we used it to help the 80%.

24+1.5=25.5
