This worksheet is about subtraction with decimals, regrouping if necessary.

Example

Work out the subtraction.

Answer

Step 1. Line up the decimal points, inserting zeros if needed for 857.40.
Step 2. Subtract, starting with the hundredths place, 2 - 0 = 2.
Step 3. Move to the tenths place. We need to regroup, so 1 in the ones place becomes 0 and 3 in the tenths place becomes 13. Subtract 13 - 4 = 9.
Step 4. Move to the ones place, to the left of the decimal. We need to regroup, so 9 in the tens place becomes 8 and 0 in the ones place becomes 10. Subtract 10 - 7 = 3.
Step 5. Subtract in the tens place 8 - 5 = 3 and then subtract in the hundreds place, 8 - 8 = 0. 
Answer: 33.92
