- 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
