Question

# Convert 1 metre(m) 4 decimetre(dm) into metre(m).

$\Rightarrow \dfrac{1}{{10}}$ m = 1 dm
$\Rightarrow$1 dm = $\dfrac{1}{{10}}$m
$\Rightarrow$4 dm = $\dfrac{4}{{10}}$m
1 m 4 dm = 1 m + 4 dm = 1 m + $\dfrac{4}{{10}}$m = $1 + \dfrac{4}{{10}}$m = $\dfrac{{10 + 4}}{{10}} = \dfrac{{14}}{{10}} = 1.4$ m
