Answer

The incision is 7.6 centimeters long.

Work Step by Step

To find the incision in centimeters, we need to multiply 76 millimeters by the ratio that converts millimeters to centimeters. The ratio that converts millimeters to centimeters is $\frac{0.1\ centimeter}{1\ millimeter}$. After all, when multiplied by the original expression, this ratio cancels our the undesired units and leaves us with the desired units, centimeters. So, 76 $\times$ $\frac{0.1\ centimeter}{1\ millimeter}$ = 7.6 centimeters.
