Question

Express as meters using decimal:

$15\mathrm{cm}$.

Answer 1

Convert the unit from centimeter to meter:

Given length: $15\mathrm{cm}$.

It is known that, $1\mathrm{cm}=\frac{1}{100}\mathrm{m}=0.01\mathrm{m}$.

Thus, $15\mathrm{cm}=\left(15\times 0.01\right)\mathrm{m}=0.15\mathrm{m}$.

Hence $15\mathrm{cm}$ can be expressed in meters as $0.15\mathrm{m}$.
