In this worksheet, we will learn about the subtraction of numbers with one decimal place
Find the difference between the two numbers.
328.7 - 400.9 = __________
In this example, 400.9 is larger than 328.7, so we reverse the calculation to become
400.9 - 328.7
Then we set out the subtraction, being careful to line up the decimal points and to borrow if necessary when subtracting a larger number from a smaller one.
Finally, change the sign to get the final answer -72.2
So 328.7 - 400.9 = -72.2
