Answer:

A : 45

B : 22.5

second page is 4.5

third page is is 25.5

fourth page is 62.5

Answer:

25% of £90 = £22.50

25% of £18 = £4.50

85% of 30 = £25.50

15% of £24 = £3.60

Step-by-step explanation:

For some of the answers, I can see you've got the digits correct, but it is important that you add the 0 for the .5 since it is in money terms. e.g. not 4.5, but £4.50.

With percentages, it is useful to break them down into easier percentages to solve. For example, instead of thinking of 15%, think of 10% + 5%. Finding 10% of a number is easy - divide it by 10. So 10% of 24 would be 2.4. And 5% of 24 is just 10% divided by 2, because 10 divided by 2 is 5. So 5% of 24 is 2.4 divided by 2, so 5% of 24 = 1.2

10% + 5% = 15% = 2.4 + 1.2 = 3.6

And because it is in money terms, we need to add the 0, to make it:

£3.60.
