Multiplying Decimals By 10 Or 100 Missing Factor Practice Activities
Grade 6 worksheets for finding the missing factor when a decimal is multiplied by 10 or 100.
Practice that builds confidence
Understanding the missing factor
These Grade 6 math worksheets help students find the missing factor in decimal multiplication equations involving 10 or 100. Instead of only calculating products, children reason backward from equations such as ___ × 10 = 7.4 or 0.36 × ___ = 36.
The printable activities build fluency with place value, powers of ten, decimal movement, and inverse operations. Students practise identifying whether the missing factor is a decimal, 10, 100, or another value that makes the equation true.
This collection focuses on equations where one factor is unknown and the multiplier or relationship involves 10 or 100. Students connect multiplication by 10 and 100 to place-value shifts: tenths become ones, hundredths become ones, and each digit changes value without changing order. The missing number is found by thinking, “What would make this equation true?”
How the skill progresses
Problems may begin with straightforward forms such as 0.8 × 10 = ___, then move to missing-factor forms like ___ × 10 = 8 or 0.45 × ___ = 45. Students learn to compare the starting number and the product, notice whether the value became 10 times or 100 times as large, and choose the factor that explains the change.
Parent practice routine
At home, ask your child to read each equation aloud before writing an answer. Have them underline the known decimal and product, then say whether the product is 10 times or 100 times greater. For example, if ___ × 100 = 23, they can reason that 23 divided by 100 is 0.23, so the missing factor is 0.23.
Classroom uses for teachers
Teachers can use these worksheets for decimal review, small-group reteaching, math centers, or quick exit checks after a lesson on multiplying decimals by powers of ten. They also work well for partner discussion because students must justify the missing factor, not just perform a routine calculation.
Common errors to watch for
Some students add zeros to decimals without considering place value, writing 0.6 × 10 = 0.60 instead of 6. Others move the decimal in the wrong direction when working backward. Encourage students to estimate first: multiplying by 10 or 100 makes a positive decimal larger, so the answer should reflect that relationship.

After the child completes the worksheet independently, parents and teachers can use the answer support or answer key information to check the work, review mistakes, and choose the next practice step.
Why iBloom worksheets help
The activities give repeated, focused practice with one important Grade 6 decimal skill. A useful child-friendly strategy is: compare, count, and check. Compare the two numbers, count whether the value changed by one or two place-value positions, then check by multiplying the missing factor back into the equation.
Helpful answers
Frequently asked questions
What skill do these worksheets practise?
They practise finding the missing factor in decimal multiplication equations where the relationship involves multiplying by 10 or 100.
How is this different from regular decimal multiplication practice?
Students are not only finding products. They also work backward from a product or known factor to decide what missing number makes the equation true.
What place-value idea should students understand first?
Students should understand that multiplying by 10 or 100 makes each digit worth 10 or 100 times as much, so the decimal value changes predictably.
What is a common mistake with these problems?
A common mistake is adding zeros or moving the decimal point without checking whether the number should become larger and by how many place-value positions.
How can parents help with a difficult problem?
Ask the child to compare the known decimal and product, decide whether the change is by 10 or 100, and then check by multiplying the missing factor back into the equation.
