213 is 30% of what amount

WITCHER [35]

Start by calling the unknown amount 'x'. We can then set up a relationship to represent the question:

$213 = (30\%) \times x$
or
$213=0.3x$

and then solve for x, by dividing both sides of our equation by 0.3

$\frac{213}{0.3}=\frac{0.3x}{0.3}$
$710=x$

213 is 30% of 710

To check: $710 \times 0.3 = 213$
