Dividing Whole Numbers By 10 100 1000 Missing Dividend Or Divisor Practice Activities
Printable Class 6 maths practice for finding missing dividends or divisors when whole numbers are divided by 10, 100 and 1000.
Practice that builds confidence
What children learn
These Class 6 mathematics worksheets help children practise division of whole numbers by 10, 100 and 1000 when either the dividend or the divisor is missing. Learners use place value, decimal movement and inverse operations to complete number sentences accurately.
The printable activities include fill-in-the-blank equations, mixed missing-number problems and examples that connect whole-number division with decimal quotients. They are designed for focused practice within Decimals Division.
In this skill, children move beyond direct sums such as 450 ÷ 10 and learn to reason from any part of a division equation. In ? ÷ 100 = 36, the missing dividend is found by multiplying 36 by 100. In 720 ÷ ? = 7.2, the missing divisor must be 100 because the number has been divided by two place-value steps. This strengthens the link between division, multiplication and place value.
How the practice progresses
The worksheets begin with familiar powers of 10 and whole-number results, then include decimal quotients where dividing a whole number shifts the decimal point left. Children practise identifying whether they need to find the starting number or the divisor. Questions may use 10, 100 or 1000, so learners must attend to the number of places rather than simply count zeroes.
Parent routine for home practice
Ask your child to read each equation aloud: “something divided by 100 equals 48” or “630 divided by something equals 6.3.” Then have them decide: is the blank before or after the division sign? If the dividend is missing, multiply the answer by 10, 100 or 1000. If the divisor is missing, compare the dividend and quotient and ask how many place-value moves were made. Encourage checking by substituting the answer back into the original equation.
Common errors and quick strategy
Watch for children moving the decimal in the wrong direction, writing 36 instead of 3600 for ? ÷ 100 = 36, or assuming the divisor is always the number of zeroes they see. A child-friendly strategy is: “Find the blank, choose the opposite operation, then check.” For missing dividends, go backwards with multiplication. For missing divisors, ask, “Did the number become 10 times, 100 times or 1000 times smaller?”

Classroom use and why iBloom worksheets help
Teachers can use these sheets after introducing decimal division by powers of 10, as a maths centre task, quick revision, homework or small-group support. The focused format helps pupils practise one precise idea without distraction: missing dividend or missing divisor in division by 10, 100 and 1000. iBloom worksheets help because the problems are arranged to build confidence gradually, with enough variety to reveal whether children understand the relationship or are only applying a memorised rule.
Helpful answers
Frequently asked questions
What does missing dividend mean in these worksheets?
The dividend is the number being divided. In a question like ? ÷ 100 = 42, children find the missing dividend by using the inverse operation: 42 × 100 = 4200.
How can a child find the missing divisor?
They compare the dividend and the quotient to see whether the number became 10, 100 or 1000 times smaller. For example, 560 ÷ ? = 5.6 gives a divisor of 100.
Do these questions include decimal answers?
Yes. Since the topic belongs to Decimals Division, some whole numbers divided by 10, 100 or 1000 lead to decimal quotients, such as 47 ÷ 10 = 4.7.
What is the most common mistake in this skill?
Many children move the decimal point in the wrong direction or forget to use multiplication when the dividend is missing. Substituting the answer back into the equation helps catch this.
How should these worksheets be used for revision?
Let the child first mark whether the blank is the dividend or divisor, solve the sum, and then check by completing the full division sentence. This builds accuracy and reasoning.
