Question

Express some numbers as meters using decimals.
$15cm$
$6cm$
$419cm$

Answer 1

$\left(A\right)15cm=\frac{15}{100}=0.15m$

$\left(B\right)6cm=\frac{6}{100}=0.06m$

$\left(C\right)7cm=\frac{7}{100}=0.07m$

$\left(D\right)419cm=\frac{419}{100}=4.19m$

or $4m19cm$

as $1cm=\frac{1}{100}m$

or $1m=100cm$
