2 minutes is equal to 2*60 = 120 seconds. 30 seconds is equal to `(30/120)*100% = (100/4)% = 25%`

30 seconds is 25% of 2 minutes.

Shelly, we know that 30 seconds is half a minute. how many of them make two minutes? A: 4.
Then 100/4=25,

meaning the answer therefore is 25%

Percentage refers to a ratio where the denominator is 100. A statement like x percent of y means x/y expressed as an equivalent fraction that has denominator 100.

To determine what percentage of 2 minutes is 30 seconds first express 2 minutes in terms of seconds. As there are 60 seconds in a minute 2 minutes is 2*60=120 seconds.

30 seconds is 30/120 = 1/4 of 2 minutes.

As a percentage 1/4 = 1/4*(25/25)= 25/100 = 25%

30 seconds is 25℅ of two minutes.
