Teaching tips and what to try next

Multiply the divisor and the dividend by the same power of ten so the divisor is a whole number (1.2 ÷ 0.3 becomes 12 ÷ 3); the quotient does not change. Have your child estimate first. Review Dividing Decimals by Whole Numbers, then apply all four operations in Decimal Word Problems.

10 versions, each with its own answer key

Same skill and layout, a fresh set of problems in every version, so children can keep practicing without repeating a page. Problems are not repeated between versions unless a skill has only a small number of possible problems (for example, the addition facts within 10).

About this worksheet

Dividing by a decimal is one of the last big steps in fifth grade decimal work. This worksheet has 18 problems in three parts. Part A divides tenths by tenths, such as 4.2 / 0.7. Part B divides hundredths by hundredths, such as 5.36 / 0.67. Part C has a tenths divisor and a quotient with tenths, such as 3.45 / 0.5 = 6.9.

Every problem divides evenly, so children can focus on the method instead of long remainders. Each of the 10 versions has new numbers.

How to use it: the key idea is that multiplying both numbers by the same power of 10 does not change the quotient. So 4.2 / 0.7 is the same as 42 / 7, and 5.36 / 0.67 is the same as 536 / 67. Have your child move the decimal point in the divisor until it is a whole number, move it the same number of places in the dividend, and then divide. A quick estimate helps check the answer: 3.45 / 0.5 means "how many halves are in about 3.5?", so the answer should be about 7.

The answer key lists every quotient. For more practice, see our Dividing Decimals by Whole Numbers worksheet and our Powers of 10 worksheet.
