5 p/1 pound = 5 p/100 p = 1/20
20/100 = 1/5
20p is 1/5 of a GBP
20 = 4p + 5 +p 20 = 5p + 5 5p = 20 - 5 = 15 5p = 15 p = 15/5 = 3

To answer your question, there are 84 possible ways. Once you find out how many different ways there are for 6 twenties and 5 twenties, you should notice the pattern that shows that the total amount for each twenty goes up by four each time, due to ever twenty equaling 4 fives, giving four more possibilities. Since there are only 6 twenties you can use, simply add 4+8+12+16+20+24 which equals 84. Below, I have written each possibility for your use.

If 5*(p + 6) = 25 then p is -1
1/p=x/5 x=5/p so 5/p pages 1/p=x/5 x=5/p so 5/p pages
5/p p - 5 p + 5 p/5 1- p + 5
1 pound. 20% means 20/100. 20/100 = 1/5. 1/5 * 5 = 5/5= 1.
To find the value of p, simply use addition, subtraction and division to isolate p: 5p -1 = 2p + 20 5p - 2p - 1 = 2p - 2p + 20 3p - 1 + 1 = 20 + 1 3p/3 = 21/3 p = 7 The value of p is 7.
