The document is about percentages and how to convert fractions and decimals to percentages using a "hundred squares" chart. It explains that the percentage symbol is % and is read as "percent". It then shows a hundred squares chart and explains how to use it to convert fractions of hundredths to percentages by shading the appropriate number of squares. Some examples of conversions are worked out. It also discusses how to convert percentages to fractions and decimals.

91 92 93 94 95 96 97 98 99 100

6. How to use it??
• The function of that squares is to convert
fractions of hundredths to
percentage
• E.g. : 16
= 16%
100
42% = 42
100

7. f 16% the squares should
be :
1 2 3 4 5 6 7 8 9 10
11 12 13 14 15 16 17 18 19 20
21 22 23 24 25 26 27 28 29 30
31 32 33 34 35 36 37 38 39 40
41 42 43 44 45 46 47 48 49 50
51 52 53 54 55 56 57 58 59 60
61 62 63 64 65 66 67 68 69 70
71 72 73 74 75 76 77 78 79 80
81 82 83 84 85 86 87 88 89 90
91 92 93 94 95 96 97 98 99 100
The squares must be shaded until
16th square. So it shows the value of

8. Lets try this!

11. 1. What is the percentage of the shaded
square below?
7% C ) 71%
B ) 17% D ) 27%

12. 2. What is the percentage?
40% 45%
50% 55%

15. Now we move to the next
level!
• Converting proper fractions
of tenths to percentage

16. Test your mind…
• Write this fraction as a percent.
30
=
100
A 3% C 13%
B 33% D 30%

19. • Converting percentage to
fraction in its simplest form

20. Converting percentage to
decimal number
• Percentage can be converted into decimal
• Lets see the example :
CLICK ME!!!!
• Now lets watch and learn

22. Try this!!
• Write the percentage below as decimal
7.3 0.73
73% 0.073 73.0

24. Try Again!!

25. Review
• Every decimal and fraction can be change into
percentage and vice versa
• Think about percentage, think also about the
square of hundred
25%
100%

27. Good bye!!
