Write the number in numerical form.

twenty-seven thousandths



Round the number to the indicated place.

$12.59572 to cents

Answer 1

• sixty-six millionths
• 0.027
• $12.60

Explanation:

(a) The least-significant digit is in the 6th place to the right of the decimal. Numbers in that place have the value "millionths." The number is 66 times 1 millionth, or sixty-six millionths.

__

(b) 27/1000 = 0.027 . . . . the least-significant digit goes in the "thousandths" place

__

(c) The digit to the right of the "cents" place is 5. This is more than 4, so 1 must be added to the cents place when rounding. $12.59 + 0.01 = $12.60.
