The pie chart shows the proportions of students in a year group who played basketball, football, and volleyball. Given that there are 108 students in the year, complete the table.

Here we have our pie chart. Here we can see half of the circle is for students who play football. And then the other half is split equally between volleyball and basketball. So each of these will be a fourth.

So if half of the students play football, we need to take one-half times 108. And we get 54, so let’s put that in the place for football in our table. One-fourth of the students play volleyball. So one-fourth times 108 would be 27.

And now we do the same for basketball. And just like in volleyball, one-fourth times 108 gives us 27. So now our table is complete. Just to be safe, let’s go ahead and add all of our numbers together and make sure that it equals the total number of students, 108. And 27 plus 27 plus 54 is indeed 108. So our table is complete.
