 # Subtract Numbers with Decimal Places (2)

In this worksheet, students subtract numbers with decimal places. Key stage:  KS 2

Curriculum topic:   Number: Fractions, Decimals and Percentages

Curriculum subtopic:   Use up to Three Decimal Places

Difficulty level:   ### QUESTION 1 of 10

In this worksheet, we will learn about the subtraction of numbers with decimals.

Example:

Question:

Find the difference between  17.5 - 2.75.

Finding the difference means subtracting, so we need to work out 17.5 - 2.75

Step 1. Line up the decimal points and add zeros when needed, next to the 17.50.

Step 2. Subtract, starting with the hundredths place. We need to regroup, so 5 in the tenths place becomes 4 and 0 in the hundredths place becomes 10. Subtract 10 - 5 = 5.

Step 3. Move to the tenths place and regroup with the ones place (to the left of the decimal), so the 7 becomes 6 and the 4 in the tenths place becomes 14. Subtract 14 - 7 = 7.

Step 4. Move to the ones place, to the left of the decimal. Subtract 6 - 2 = 4 and then in the tens place, 1 - 0 = 1.

The answer is 14.75. Subtract as normal, but remember to line up the decimals so that the place value in the answer is correct. Find the difference between the two numbers

• Question 1

Find the difference between the two numbers

729.7 - 290.5 = ________

439.2
EDDIE SAYS
Step 1. Line up the decimal points. Step 2. Subtract, starting with the tenths place, 7 - 5 = 2. Step 3. Move to the ones place, to the left of the decimal, and subtract 9 - 0 = 9. Step 4. Move to the tens place. We need to regroup, so 7 in the hundreds place becomes 6 and 2 in the tens place becomes 12. Subtract 12 - 9 = 3. Step 5. Subtract in the hundred place, 6 - 2 = 4. Answer: 439.2

EDDIE SAYS
Step 1. Line up the decimal points. Step 2. Subtract, starting with the tenths place. We need to regroup, so 3 in the ones place becomes 2 and 1 in the tenths place becomes 11. Subtract 11 - 7 = 4. Step 3. Move to the ones place, to the left of the decimal. We need to regroup, so 3 in the tens place becomes 2 and 2 in the ones place becomes 12. Subtract 12 - 8 = 4. Step 4. Move to the tens place. We need to regroup, so 7 in the hundreds place becomes 6 and 2 in the tens place becomes 12. Subtract 12 - 9 = 3. Step 5. Subtract in the hundreds place, 6 - 6 = 0. Answer: 34.4
