Question

arpenter installing cabinets uses thin pieces of material called shims to fill African elephants The carpenter uses four shims to fill a gap that is 1.5 centimeters wide. The widths of three of the shims are 0.75 centimeter, 0.125 centimeter, and 0.1 centimeter. What is the width of the fourth shim

Answer 1

0.525 cm

1) Gathering the data

4 shims

1.5 cm wide

0.75 cm

0.125 cm

0.1 cm

2) Considering that we are going to place those shims, side by side, we can add them up.

0.75 + 0.125 + 0.1 = 0.975 cm

Since there has to be a fourth one we can write, subtracting from 1.5 (the width of the gap):

1.5 -0.975 = 0.525

3) So to fill that gap, we're going to need another shim whose measure is 0.525 cm
