Question

Express as metres using decimals: $9\mathrm{m}7\mathrm{cm}$

Answer 1

Convert from centimeter to meter

Given, $9\mathrm{m}7\mathrm{cm}$

Which is $9\mathrm{m}+7\mathrm{cm}$

We know that,

$\begin{array}{rcl}1\mathrm{cm}& =& 0.01\mathrm{m}\\ & \Rightarrow & 7\mathrm{cm}=7\times 0.01\\ & =& 0.07\mathrm{m}\end{array}$

Thus,

$\begin{array}{rcl}9\mathrm{m}7\mathrm{cm}& =& 9\mathrm{m}+0.07\mathrm{m}\\ & =& 9.07\mathrm{m}\end{array}$

Therefore, $9\mathrm{m}7\mathrm{cm}$ can be expressed in decimal as $9.07\mathrm{m}$.
