Question

Convert the following length from mm to cm using decimals.

$12$cm $46$mm

Answer 1

Converting millimeter to centimeter

Let us first convert $46$mm to cm

We know that the $1$mm $=\frac{1}{10}\mathrm{cm}=0.1$cm

Therefore, $46$mm $=46\times \frac{1}{10}=\frac{46}{10}=4.6$cm

Now, $12$cm $46$mm $=(12+4.6)=16.6$cm

Hence, $12$cm $46$mm $=16.6$cm
