Worked example

Given: 36 points earned on a 45-point assignment.
  1. Divide earned by total: 36 ÷ 45 = 0.8
  2. Multiply by 100: 0.8 × 100 = 80%
Answer: The score is 80%.

Common mistakes

  • Swapping numerator and denominator: Points earned go on top; points possible go on the bottom. Swapping them invents an impossible grade over 100% or a tiny fraction.
  • Rounding too early: Carry extra decimal places through multi-step work before rounding the final percent.
  • Mixing percent and decimal forms: Enter rates in the format the calculator labels expect.
