Subtract Numbers with One Decimal Place (2)

In this worksheet, we will learn about the subtraction of numbers with one decimal place

Example:

Find the difference between the two numbers.

328.7 - 400.9 = __________

Answer:

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.

400.9

328.7

  72.2

Finally, change the sign to get the final answer -72.2

So 328.7 - 400.9 = -72.2
