Question

A carpenter who is installing cabinets uses thin peices 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?

Answer 1

The width of the fourth shim is 0.235 cm. Add the three shims, 0.75+0.125+0.09= 0.965 and subtract that from the total 1.2-0.965= 0.235 cm
