State how many minutes there are in two and a third hours.

We can break two and a third hours out into the sum of one hour and another hour and one-third of an hour. We then need to remember that there are 60 minutes in one hour. So we’ll have 60 minutes plus 60 minutes and then some other number of minutes that we’ll need to work out for one-third of an hour.

To find one-third of a number, we can divide that number by three. 60 divided by three is 20, which we can either see if we recall that six divided by three is two, so 60 divided by three is 20, or we can use a short division or bus stop method. There are two threes in six with no remainder, and there are zero threes in zero, so 60 divided by three is 20.

Finally, we just need to add all of these values in minutes together, which we can either do mentally or using a column addition method. 60 plus 60 is 120, and adding a further 20 gives 140. There are 140 minutes in two and a third hours.
