Maths Support Week 3

Next week in Maths, we will be recognising the percent symbol (%) and understand that per cent relates to ‘number of parts per hundred’ and write percentages as a fraction with denominator 100, and as a decimal.

Per cent means ‘out of 100′

The sign % stands for ‘per cent’ which means ‘out of 100′.

So:

  • 40% means 40 out of 100
  • 11% means 11 out of 100

Converting between percentages and decimals

To change a percentage to a decimal, divide by 100.
Change 48% to a decimal: 48 ÷ 100 = 0.48

To change a decimal to a percentage, multiply by 100.
Change 0.67 to a percentage: 0.67 x 100 = 67%

For extra support on this area, check out the bbc website that has a fun video on decimals and percentages for the children to use.
