Don't worry if you feel like the child above, you don't have to learn it all at once!


Let's see how it works in practice.


Example 1

Jack takes 5¼ minutes to learn his capital cities.

How many seconds is this?



1 minute = 60 seconds.

½ minute = 30 seconds.

¼ minute = 15 seconds.

5 minutes = 5 × 60 = 300 + ¼  minute = 300 + 15 = 315 seconds.

Example 2

Ahmed starts work at 9.00 a.m. and finishes at 4:30 p.m.

For how many minutes is he at work?



From 9.00 a.m. to 4 .00 p.m. is 7 hours.

30 minutes is half an hour.

So Ahmed is at work for 7½ hours.


7 hours = 7 × 60 = 420 + ½ hour  = 420 + 30 = 450 minutes.


That looks a bit simpler, doesn't it?
