Grade 5 Math · Decimal Multiplication and Division
Build Grade 5 Math skills with five 10-question practice tests on decimal multiplication, decimal division, powers of ten, decimal divisors, estimation, and real-world measurement problems.
These Grade 5 Math practice tests help students multiply and divide decimals accurately. Students practice powers of ten, counting decimal places, rewriting decimal divisors as whole numbers, estimating, and solving measurement and money problems.
Write the operation clearly, use place-value reasoning, and check whether the size of the answer makes sense. When the divisor is a decimal, multiply both the dividend and divisor by the same power of ten so the divisor becomes a whole number.

Correct answer: B
The correct answer is Count the total decimal places in the factors and place that many in the product..
The product has as many decimal places as the total number of decimal places in the factors.
Multiply as whole numbers, then place the decimal point so the product has the total number of decimal places in the factors.
Multiply both the dividend and divisor by the same power of ten so the divisor becomes a whole number, then divide.
