2. 2. In a SATs Paper B you might be asked to work out what percentage of a grid is shaded:
3. 3. For example: Here is a grid of 20 tiles. What percentage of the tiles are shaded blue? Firstly count up the number of shaded tiles:
4. 4. For example: Here is a grid of 20 tiles. What percentage of the tiles are shaded blue? Firstly count up the number of shaded tiles: There are 6
5. 5. For example: Here is a grid of 20 tiles. What percentage of the tiles are shaded blue? Firstly count up the number of shaded tiles: There are 6 As a fraction: 6/20 of the grid is shaded
6. 6. For example: Here is a grid of 20 tiles. What percentage of the tiles are shaded blue? Now convert 6/20 to a fraction with a denominator of 100
7. 7. For example: Here is a grid of 20 tiles. What percentage of the tiles are shaded blue? Now convert 6/20 to a fraction with a denominator of 100 6 20 = X5
8. 8. For example: Here is a grid of 20 tiles. What percentage of the tiles are shaded blue? Now convert 6/20 to a fraction with a denominator of 100 6 20 = 100 X5
9. 9. For example: Here is a grid of 20 tiles. What percentage of the tiles are shaded blue? Now convert 6/20 to a fraction with a denominator of 100 X5 6 = 100 20 X5
10. 10. For example: Here is a grid of 20 tiles. What percentage of the tiles are shaded blue? Now convert 6/20 to a fraction with a denominator of 100 X5 30 6 = 100 20 X5
11. 11. For example: Here is a grid of 20 tiles. What percentage of the tiles are shaded blue? This fraction can then be converted directly to a % X5 30 6 = 100 20 X5
12. 12. For example: Here is a grid of 20 tiles. What percentage of the tiles are shaded blue? This fraction can then be converted directly to a % X5 30 6 = 100 20 X5 = 30%
13. 13. Another example: Here is a pattern on a grid. What percentage of the tiles are shaded green?
14. 14. Another example: Here is a pattern on a grid. What percentage of the tiles are shaded green? Firstly count up the total number of tiles.
15. 15. Another example: Here is a pattern on a grid. What percentage of the tiles are shaded green? Firstly count up the total number of tiles. There are 50.
16. 16. Another example: Here is a pattern on a grid. What percentage of the tiles are shaded green? Firstly count up the total number of tiles. There are 50. Then count up the number of tiles that are shaded green.
17. 17. Another example: Here is a pattern on a grid. What percentage of the tiles are shaded green? Firstly count up the total number of tiles. There are 50. Then count up the number of tiles that are shaded green. There are 14
18. 18. Another example: Here is a pattern on a grid. What percentage of the tiles are shaded green? Firstly count up the total number of tiles. There are 50. Then count up the number of tiles that are shaded green. There are 14 As a fraction, this is written as 14/50
19. 19. Another example: Here is a pattern on a grid. What percentage of the tiles are shaded green? Now convert 14/50 to a fraction with a denominator of 100
20. 20. Another example: Here is a pattern on a grid. What percentage of the tiles are shaded green? Now convert 14/50 to a fraction with a denominator of 100 14 50 =
21. 21. Another example: Here is a pattern on a grid. What percentage of the tiles are shaded green? Now convert 14/50 to a fraction with a denominator of 100 14 50 = X2
22. 22. Another example: Here is a pattern on a grid. What percentage of the tiles are shaded green? Now convert 14/50 to a fraction with a denominator of 100 14 50 = 100 X2
23. 23. Another example: Here is a pattern on a grid. What percentage of the tiles are shaded green? Now convert 14/50 to a fraction with a denominator of 100 X2 14 = 100 50 X2
24. 24. Another example: Here is a pattern on a grid. What percentage of the tiles are shaded green? Now convert 14/50 to a fraction with a denominator of 100 X2 28 14 = 100 50 X2
25. 25. Another example: Here is a pattern on a grid. What percentage of the tiles are shaded green? This fraction can then be converted directly to a % X2 28 14 = 100 50 X2
26. 26. Another example: Here is a pattern on a grid. What percentage of the tiles are shaded green? This fraction can then be converted directly to a % X2 28 14 = 100 50 X2 = 28%
