Question

Write the following in decimal form:

$13\mathrm{m}7\mathrm{cm}$

Answer 1

$\begin{array}{rcl}13\mathrm{m}7\mathrm{cm}& =& 13\mathrm{m}+7\mathrm{cm}\\ & =& 13\mathrm{m}+7\left(\frac{1}{100}\right)\mathrm{m}[\because 1\mathrm{cm}=\frac{1}{100}\mathrm{m}]\\ & =& 13\mathrm{m}+0.07\mathrm{m}\\ & =& 13.07\mathrm{m}\end{array}$

Hence, decimal form of $13\mathrm{m}7\mathrm{cm}$ is $13.07\mathrm{m}$.
