1. Everything you need to know ….eventually
Percentages
Everything you need to know ….eventually

2. Whether you are as clever as …

3. Or as dumb as ……

4. No, I’m not saying you are stupid

5. You need to write these down

6. Percent means ….
‘out of a hundred’

7. We can write any fraction or decimal as a percentage.
Hopefully by the end of the lesson

9. Example 1
17 = 17%
100

10. Example 2 X2
23 = = 46% X2

11. Example 3 X5
17 = = 85% X5

13. Example 4 X4
13 = = 52% X4

14. Example 5
X10
8 = = 80%
X10

15. Now for slightly more difficult ones…..
Relax I said slightly!

16. Example 6 ÷2
86 = = 43% ÷2

17. Example 6 ÷3
96 = = 32% ÷3

18. Your turn… X4
21 = = 84% X4

19. Your turn… X5
12 = = 60% X5

20. One more … ÷2
148 = = 74% ÷2

21. Wordy question…
If you score 46 out of 50 in a maths test, what percentage did you get?

22. Answer…. X2
46 = = 92% X2

23. Before you start, just remember….
Some people got more than that!

24. Can also change percentages into fractions….
48% = = 12
(48 and 100 both divide by 4)

25. And another…
65% = = 13
(65 and 100 both divide by 5)

26. One for you ….
18% = = 9

27. We can even change percentages into decimals…..

28. Really easy…..
Just divide by 100

29. Example …..
53% = = 53 ÷100
100
= 0.53

30. Another one ……
68% = 68 = 68÷100
100
= 0.68

31. Last one ……
54% = 54 = 54÷100
100
= 0.54

32. That’s it for now
Time for a worksheet
