  1. 0.007 · A denominator of 1000 means thousandths, which takes three places after the decimal point.
  2. 7/1000 · 0.007 has three digits after the point, so it means 7 thousandths, or 7/1000.
  3. True · Three decimal places always means thousandths, so 0.005 is 5 thousandths, or 5/1000.
  4. 100 · 1 tenth splits into 10 hundredths, and each hundredth splits into 10 thousandths, so 1 tenth = 100 thousandths.
  5. False · 0.5 is 5 tenths, which is 500 thousandths, not 50.
  6. True · 1/100 = 10/1000, so the statement is true.
  7. 400 · Since 1 tenth is 100 thousandths, 4 tenths is 4 times as much.
  8. 100 · One tenth is 100/1000, so it equals 100 thousandths.
  9. No, they are equal · 0.4 is 4 tenths, which is 400 thousandths, the same as 0.400. Extra zeros at the end don't change the value.
  10. 600 · 0.6 is 6 tenths, and each tenth is 100 thousandths, so 6 tenths is 600 thousandths.
