Question

A physician tells her patient that her surgical incision will be 8 millimeters wide. How wide is the incision in inches?

Answer 1

Answer:

0.315 inches

Step-by-step explanation:

1 millimeter = 0.1 cm

2.54 cm = 1 in

Now convert 8 millimeters to inches

8mm x $\frac{0.1 cm}{1 mm}$ x $\frac{1 inch}{2.54 cm}$  ; multiply across and divide and cancel units

$\frac{0.8 inch}{2.54}$ = 0.315 inches

Answer 2

Answer:

0.3149608 in. wide

Step-by-step explanation:

1 milimeter=0.0393701 inches

8x0.0393701=0.3149608in. wide
