Answer key — Converting Fractions, Decimals & Percents

  1. B — 0.5. 1 ÷ 2 = 0.5.
  2. B — 3/4. 0.75 = 75/100, which simplifies to 3/4.
  3. C — 25%. 1/4 = 0.25 = 25%.
  4. C — 1/2. 50% = 50/100, which simplifies to 1/2.
  5. B — 20%. Move the decimal point two places right: 0.2 = 20%.
  6. B — 0.6. 3 ÷ 5 = 0.6.
  7. B — 0.6. Move the decimal point two places left: 60% = 0.6.
  8. C — 12.5%. 1 ÷ 8 = 0.125 = 12.5%.
  9. B — 2/5. 0.4 = 4/10, which simplifies to 2/5.
  10. C — 0.75. Move the decimal point two places left: 75% = 0.75.
