Use the proportion to convert millimeters to centimeters. 10mm/1cm=47mm/x

- The centimeter is defined as a unit of lenght. Its symbol is: "cm".

- 1 centimeter=10 milimeters.

- The milimeter is defined as a unit of lenght and its symbol is "mm".

1. If you want to convert 47 milimeters to centimeters by using proportions, you have:

10 mm/1 cm=47mm/x

2. Then, you only have to clear the "x":

(10 mm) x = (47mm) (1 cm)

x = (47 mm) (1 cm) / 10 mm

3. Therefore, the result is:

x=4.7 centimeters
