Patrick completes 13 questions every 52 minutes.
We're trying to find the time for Patrick to complete 1 packet.
Let's set these up as a fraction equation.
13/52 = 1/x, x being the variable that substitutes the time we're looking for.
13/52 can be simplified, though.
Divide both numbers by 13.
13 / 13 = 1
52 / 13 = 4
We now have:
1/4 = 1/x.
Well, this makes it easier. The numerators match, so the denominators must match as well.
x = 4.
It will take Patrick 4 minutes to complete 1 homework question.
I hope this helps!
