"Percent" or "%" means "out of 100" or "per 100", Let's call the percent we are looking for $x$ . Therefore x% can be written as $x/100$ .

We can write this as:

$x/100 = 30/48$

Now, solve for $x$ by multiplying each side of the equation by $color(red)(100)$

$color(red)(100) xx x/100 = color(red)(100) xx 30/48$

$cancel(color(red)(100)) xx x/color(red)(cancel(color(black)(100))) = 3000/48$

$x = 62.5$

30 is $color(red)(62.5%)$ of 48
