Question: What is
$\bold{4(9)/(10)}$ expressed as a decimal

Answer:
$\boxed{\bold{4.9}}$

Explanation:
$\downarrow{\downarrow{\downarrow{}}}$

Note: We are rounding our answer to a decimal place of one

[ Step One ] Separate the fraction parts

$\bold{4(9)/(10)}$
$\bold{= \ 4\ + \ (9)/(10) }$

[ Step Two ] Rewrite expression

$\bold{(9)/(10) \ = \ 9 \ / 10}$

[ Step Three ] Rewrite expression using all parts

$\bold{4(9)/(10) \ = \ 4 + \ (9 \ / \ 10)}$

[ Step Four ] Solve equation

$\bold{4 \ / \ 10 \ = \ 0.9}$

$\bold{4 \ + \ 0.9 \ = \ 4.9}$

$\bold{\rightarrow{}Rhythm \ Bot\leftarrow{}}$
