- When finding the percentage of a shape, it is important to remember that you consider the whole shape to be 100%.
2. Then you have to figure out what each part represents – if the shape is in 4 equal pieces, each piece represents 25% and so on.
The circle would represent 100%. It has been cut into 8 pieces – so we to find out what each piece represents we have to divide 100 by 8, which is 12.5%. 3 of pieces are shaded so this would be 37.5% shaded.
3. When finding the percentage of a number, there are a couple of tricks that you can use – but it’s different for every percentage.
a) You can always find 10% of a number by dividing it by 10 (this is because 10% is 100% divided by 10).
b) You can always find 1% of a number by dividing it by 100.
c) You can find 50% of a number by halving
4. If you want to use a calculator to find a percentage of a number, all you have to do is write the percentage as a decimal then multiply it by that number.
Let’s say we need to find67% of £25.
First we write67% as a decimal – 0.67
0.67 x 25 = 16.75
So, 67% of £25 = £16.75
2) Place a tick against the percentage which is equal to 0.65
3) Tick the number equivalent to 9/100
4)Chang 30% to a decimal and a fraction fraction
5) Can you charge these fraction into decimal fractions.
6) Place the correct symbol : <,>,=
