What mastery looks like

  • State that 1/5 = 20% = 0.2 and use this to find 20% of 60
  • Convert 3/4 to 75% and to 0.75
  • A shop offers 25% off a £40 item — what is the sale price?

Check your understanding

If Percentage and decimal equivalents knows that 1/4 = 25% = 0.25, can they use that to work out 25% of £80 — and also find 4/5 of 60 sweets?
