Decimals and Percent: Two Ways to Write the Same Number W1-mt_W17Kbwm0-u-s1

  1. out of 100 · Per cent means 'out of 100.' The % sign is a short way to write that.
  2. True · True. Per cent means out of one hundred, so 16% means 16 out of 100.
  3. four and six tenths · 4.6 is four and six tenths, because the 6 is one place after the point, which is the tenths place.
  4. Tenths · The first digit after the decimal point is always the tenths place.
  5. 1/2 · 0.5 means 5 tenths, and 5 tenths is the same amount as 1/2.
  6. 6.022 · 6.022 is six and twenty-two thousandths. Thousandths sit three places after the point, so twenty-two becomes 022.
  7. 0.6 · 60% means 60 out of 100, and 60/100 is 0.6.
  8. 0.602 · 60.2% means 60.2 out of 100, which is 0.602.
  9. 0.7 · 0.007 is 7 thousandths, which is 0.7 hundredths, and 0.7 out of 100 is 0.7%.
  10. 0.25 · 25% means 25 out of 100. Move the decimal point two places left to get 0.25.
