Question

What percentage of 40 minutes is 15 minutes ​

Answer 1

Answer:

Your first step is to convert the "total quantity" – in this case, two hours – into minutes. There are 60 minutes in an hour, so during that two-hour period there were 60 × 2 = 120 minutes available to you.

Now that both your time spent playing and the total time available are in the same unit, all you have to do is divide the time spent playing (45 minutes) by the total time (120 minutes):

\frac{45}{120} = 0.37512045=0.375

The result is a percentage, but it's written in decimal form. To write your answer in percentage form, multiply the decimal by 100:

0.375 × 100 = 37.5\%0.375×100=37.5%

So you spent 37.5% of your study time playing games.
