Comparing two-decimal numbers W1-mt_IegHBHERVa-s1

  1. 3.72 · The ones are both 3, so compare the tenths. 7 tenths is more than 2 tenths, so 3.72 is greater.
  2. 0.39 · All three numbers have 0 ones, so compare the tenths. 0.39 has only 3 tenths, which is less than 4 tenths or 5 tenths.
  3. 3.72 · Both start with 3, so check the tenths digit: 7 in 3.72 versus 2 in 3.27. 3.72 is bigger.
  4. True · The tenths digit in 3.72 is 7, which beats the tenths digit 2 in 3.27.
  5. 0.54 · On a number line, the number nearest to 1 is the greatest one. Comparing the tenths, 5 tenths is the greatest.
  6. £4.75 · Compare the digit right after the decimal point: 7 in £4.75 versus 5 in £4.57. £4.75 costs more.
  7. 0.39, 0.45, 0.54 · The ones are all 0, so order by the tenths digits: 3, then 4, then 5.
  8. 5 · Count the hundredths steps. 0.47 is 7 steps above 0.40 but only 3 steps below 0.50, so it is closer to 0.5.
  9. 12.08, 12.18, 12.80, 12.81 · All the times have 12 ones. Order by tenths: 0, 1, 8, 8. For the two times with 8 tenths, compare hundredths to see that 12.80 comes before 12.81.
  10. 0.39, 0.45, 0.54 · Always compare tenths first, not hundredths. The tenths digits are 3, 4, 5, so the order is 0.39, 0.45, 0.54.
