  1. 3.415 · Four hundred fifteen thousandths is 0.415, and 3 + 0.415 = 3.415.
  2. 5.062 · Sixty-two thousandths is 0.062, and 5 + 0.062 = 5.062.
  3. 4 tens (40) · 4 is two places left of the decimal point, in the tens column: 4 x 10 = 40.
  4. True · 0.5 is the same as 0.50, which is 50 hundredths, more than 45 hundredths.
  5. 0.09 · The 9 sits in the hundredths place, so it is worth 0.09.
  6. 5.062 · Sixty-two thousandths fills the hundredths and thousandths places: 0.062. With the 5 ones, that's 5.062.
  7. The hundredths: 7 vs 8 · After tied tenths, the hundredths decide: 7 vs 8, so 0.38 is greater.
  8. False · Tom is wrong: 5.62 means 62 hundredths; the correct figure is 5.062.
  9. 5 is 1/100, not 1/1000 · In 208.05, the 5 is the second digit after the decimal point, so it belongs in the hundredths place: 5x(1/100).
  10. 300 and 0.3 · The first 3 is 3 hundreds (300) and the second is 3 tenths (0.3).
