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.
