Question

Which ratio is equivalent? 8 cm to 20 mm

Answer 1

Given the ratio:

8 cm to 20 mm

first convert from cm to mm

1 cm = 10 mm

so, 8 cm = 8 * 10 mm = 80 mm

so, the ratio will be :

8 cm to 20 mm = 80 mm to 20 mm =

$\frac{80\operatorname{mm}}{20\operatorname{mm}}=\frac{80}{20}=\frac{8}{2}=\frac{4}{1}=4\colon1$

so, the answer is: 8 cm to 20 mm = 4 : 1
