## Elementary Algebra

To express the length of the cut in inches, we need to multiply it by the ratio that converts centimeters to inches. The ratio that converts centimeters to inches is: $\frac{0..393\ inch}{1\ centimeter}$. So, 12 centimeter $\times$ $\frac{0.393\ inch}{1\ centimeter}$ = 12 $\times$ 0.393 inch= 4.7 inches The cut is 4.7 inches long.
