#### Answer

$$Hundred=1,543,700$$ $$Ten=1,543,680$$ $$Unit=1,543,679$$ $$Tenth=1,543,679.0$$ $$Hundredth=1,543,679.00$$ $$Thousandth=1,543,679.000$$

#### Work Step by Step

Hundreds place = nearest 100 (in the whole numbers) So, 1,543,679 rounded to the hundreds place is $1,543,700$ Tens place = nearest 10 (in the whole numbers) So, 1,543,679 rounded to the tens place is $1,543,680$. Unit = nearest 1 (in the whole numbers) So, 1,543,679 rounded to the unit is $1,543,679$. Because our number doesn't have any decimals, the rounded numbers are the same as the unit-place-rounding. Tenths place = to the nearest 10 (in the decimals) So, 1,543,679 rounded to the tenth place is $1,153,679.0$ Hundredths place = to the nearest 100 (in the decimals) So, 1,543,679 rounded to the hundredths place is $1,153,679.00$ Thousandths place = to the nearest 1000 (in the decimals) So, 1,543,679 rounded to the thousandths place is $1,153,679.000$
