Division of Decimals I. Dividing a Decimal by a Whole Number Dividing a decimal by a whole number is similar to dividing whole numbers. One must only be sure to line up the decimal point of the dividend with that of the quotient. Example Divide 143.22 ÷ 6 Solution 23 . 87 6 | 143 . 22 12 Hence 143.22 ÷ 6 = 23.87 Example Divide 41.472 ÷ 12 Solution . 456 12 | . 472 36 Hence 41.472 ÷ 12 = 3.456 Exercises Divide A. 0.4544 ÷ 8 B. 0.0357 ÷ 17 II. Dividing and Rounding Decimals Typically division problems yield remainders. When this is the case we usually do not write the quotient as a mix of decimal and fraction but rather round to an indicated decimal place. Since rounding involves looking at the digit to the right, we need to find this digit when we do this division. If necessary, we pad the number with zeros to the right. Example

Divide and round to the nearest hundredth. 3.64 ÷ 7 Solution Since we need to round to the nearest hundredth, we will need to see the thousandths digit. We rewrite 3.650 ÷ 7 0 . 521 7 | 3 . 650 35 15 14 10 7 END HERE Since 1 < 5

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
