Come si scrive il 30% come frazione?

Risposta:

$\frac{3}{10} = 0.3$ $3/10=0.3$

Spiegazione:

Per cent means $out of one hundred$ $color(blue)"out of one hundred"$

$\Rightarrow 30 % = \frac{30}{100}$ $rArr30%=30/100$

which may be simplified by cancelling by 10.

$30/100=cancel(30)^3/cancel(100)^10=3/10" as a proper fraction"$

and $3/10=3÷10=0.3" as a decimal fraction"$
