Acarpenter who is installing cabinets uses thin pieces of material called shims to fill gaps. the carpenter uses four shims to fill a gap that is 1.2 centimeters wide. three of the shims are 0.75 centimeter, 0.125 centimeter, and 0.09 centimeter wide. what is the width of the fourth shim?

Add up all the shims lengths that you know of right now

.75 + .125 + .09 = ?

That equals .965

The fourth shim is how ever many more centimeter until 1.2

To find this out... subtract

1.2 - .965

Your answer to this equation would be the length of the fourth shim.

1.2 - .965 = .235

The fourth shim is .235 centimeters long :)
