Question

Express $243m86cm$ as meters using decimals

Answer 1

Step 1

Convert the centimeter part into the meter

We know that

$$\begin{gathered} 1m=100cm \\ \Rightarrow 1cm=\frac{1}{100}m \\ \Rightarrow 86cm=\frac{86}{100}m=0.86m \end{gathered}$$

Step 2

Add both meter parts

$243m+0.86m=243.86m$

Hence $243m86cm$ can be represented as $243.86m$
