Hi Anne,
 
If you know how long the sidewalk is, 42 inches, then you just need to know how many times you'll have 20 inches to cut. To find out how many times a number would fit into another, you divide the two numbers. In this case, we would divide 42 by 20, looking like this: 42 ÷ 20

When I do it I get 2 Remainder 2 (or 2.1 if you do in a calculator).

We would ignore the decimal/remainder part of the answer since you can't make a fractional cut- so, Chad will cut the sidewalk twice.
