Multiplying Decimals 1 Digit By Whole Numbers Practice Activities
Printable Grade 5 math practice for multiplying tenths by whole numbers using place value, vertical multiplication, and real-world problems.
Practice that builds confidence
Build from tenths
These Grade 5 printable worksheets help students multiply decimals with one digit after the decimal point by whole numbers. Children practise seeing a decimal such as 3.4 as 34 tenths, multiplying, then placing the decimal point correctly in the product.
Activities include vertical multiplication, word problems, missing-number items, and checks that connect multiplication to repeated addition and place value. The focus is accuracy, neat work, and explaining why the answer is reasonable.
Students begin by treating 1-digit decimals as tenths: 2.7 × 6 means 27 tenths × 6 = 162 tenths, or 16.2. This place-value view helps multiplication feel logical instead of like a decimal-point trick. Some problems encourage estimation with nearby whole numbers, so 4.8 × 3 should be close to 5 × 3.
Progression across the practice
The collection moves from familiar whole-number facts to products that require regrouping. Vertical formats help students organize digits, while word problems ask them to connect decimal multiplication to money, measurement, distance, and quantities. Missing-number questions strengthen inverse thinking and help children notice whether a product is too large or too small.
Parent routine at home
Pick 6 to 8 problems and ask your child to read each decimal aloud, such as “six and two tenths.” Have them estimate first, multiply the digits as whole numbers, count the one decimal place in the factor, and compare the answer to the estimate. End with one quick real-life question, such as 1.5 pounds of apples at 4 times the amount.
Classroom uses for teachers
Use these sheets for warm-ups after a place-value mini lesson, small-group reteaching, math centers, homework, or exit tickets. Teachers can also ask students to solve one item two ways: as tenths and with the standard algorithm. This makes it easier to see who understands the value of the digits and who is only moving the decimal point by memory.
Common errors to watch for
Students may line up decimal points as if they were adding, forget to regroup, or put the decimal in the product without checking reasonableness. A child-friendly strategy is: “Estimate, multiply, place, check.” If the estimate is about 18, an answer like 1.8 or 180 should prompt a second look.

Helpful answers
Frequently asked questions
What does “1 digit decimal” mean on these worksheets?
It means the decimal has one digit after the decimal point, such as 2.4, 6.8, or 0.7. These numbers represent tenths.
Should students line up decimal points when multiplying?
No. Lining up decimal points is useful for adding and subtracting decimals. For multiplication, students multiply the digits and then use place value and estimation to place the decimal point.
How can my child check if the decimal point is in the right place?
Ask them to estimate first using nearby whole numbers. For example, 3.9 × 5 should be close to 4 × 5, or 20, so 19.5 is reasonable but 1.95 is not.
Do these worksheets include word problems?
Yes. Along with computation practice, the worksheets include decimal multiplication in practical contexts such as measurement, money-style amounts, and repeated quantities.
When is a Grade 5 student ready for this practice?
Students are ready when they can multiply whole numbers with regrouping and understand tenths on a place-value chart or number line.
