Question

$22$ students is what percent of $55$?

Answer 1

$40$%
Explanation:
The equation for percents is
Percent * Whole = Part
So all you have to do is identify the parts of the equation. We don't know the percent, but we know everything else, so we can plug what we know into the equation
$P\times 55=22$
$\frac{55}{22}=P$
$P=0.4=40$%
