Subtracting Decimals From Whole Numbers 1 3 Decimal Digits Practice Activities
Grade 6 worksheets for subtracting 1-, 2-, and 3-digit decimals from whole numbers using decimal alignment, zeros, and regrouping.
Practice that builds confidence
Skill focus: whole numbers minus decimals
These Grade 6 decimal subtraction worksheets help students subtract tenths, hundredths, and thousandths from whole numbers, such as 8 - 2.45 or 30 - 0.076. Children practise lining up decimal points, adding placeholder zeros, and regrouping across place values.
The printable activities include clear computation practice for the Decimals Addition Subtraction unit, with problems arranged to build confidence from simpler tenths to more detailed thousandths. Students learn to treat a whole number as an equivalent decimal before subtracting.
This collection targets one precise Grade 6 skill: subtracting a decimal with 1, 2, or 3 decimal digits from a whole number. Students see that 12 can be written as 12.0, 12.00, or 12.000, depending on the number being subtracted. That idea supports accurate place-value subtraction and prevents guessing based on the number of digits.
How the practice progresses
The work begins with tenths, where students may solve 6 - 2.4 by thinking of 6.0 - 2.4. It then moves to hundredths and thousandths, where alignment matters even more. Problems such as 15 - 3.87 and 40 - 0.625 require students to add zeros, regroup from ones to tenths, and continue regrouping across hundredths when needed.
A practical parent routine
At home, ask your child to read each problem aloud as “whole number minus decimal.” Have them rewrite the whole number with the same number of decimal places as the subtrahend, then solve vertically. After every few problems, ask, “Is the answer less than the whole number? Does it make sense?” This quick estimate check catches many place-value slips.
Classroom uses for teachers
Teachers can use these pages for guided practice after a decimal place-value lesson, independent math centers, homework, or a short review before mixed decimal addition and subtraction. They also work well for small groups: one student aligns the decimal points, one adds placeholder zeros, and one explains the regrouping path.
Common errors and a child-friendly strategy
Watch for students stacking numbers by the right edge instead of by decimal points, forgetting to write zeros, or subtracting the whole number from the decimal because the decimal “looks longer.” A simple strategy is: Line it, zero it, regroup it, check it. Line up decimal points, write needed zeros, regroup carefully, then check that the answer is reasonable.

Why iBloom worksheets help
The worksheets keep the focus narrow so students can master the exact obstacle: subtracting a decimal from a whole number without losing place value. The progression from 1 to 3 decimal digits gives repeated practice with the same structure while gradually increasing attention to precision.
Helpful answers
Frequently asked questions
What does it mean to subtract a decimal from a whole number?
It means taking away a decimal amount from a whole number, such as 9 - 2.35. Students rewrite the whole number as 9.00 so the hundredths, tenths, ones, and decimal points line up correctly.
Why do students add zeros after the whole number?
Zeros make the whole number show the same decimal places as the number being subtracted. For example, 14 - 6.708 becomes 14.000 - 6.708, which makes the place-value subtraction clear.
Which decimal places are practised in these worksheets?
The practice covers decimals with 1, 2, and 3 digits after the decimal point: tenths, hundredths, and thousandths.
What is the most common mistake in this skill?
A common mistake is lining up the numbers by the last digit instead of lining up the decimal points. This can put tenths under ones or hundredths under tenths, changing the value of the problem.
How can my child check an answer quickly?
Your child can estimate first. In 20 - 4.86, the answer should be a little more than 15 because 4.86 is close to 5. If the exact answer is far from that, they should recheck the alignment and regrouping.
