The table shows how the seats in a plane are distributed.

Which circle graph displays these data?
 

 

Type of Seat                         Number of Seats

First class                                         10

Business class                                  10

Economy                                           30

You find the precent something is of a whole like this: \(\frac{\text{part}}{\text{whole}}\)

There are 10 first class seats, 10 business class seats and 30 economy seats on the plane so there are 10+10+30=50 total seats.

To find the precent of first class seats, \(\frac{\text{number of first class seats}}{\text{total seats}}=\frac{10}{50}=\frac{20}{100}=20 \text{%}\) of the seats on the plane are first class.

Only the third pie chart has the number of first class seats as 20%, so that must be the answer, but lets double check the rest.

 

Buesness class: There are also 10 buesness class seats, which is the same number of first class seats so it must also be 10% buesness class. This matches the third pie chart.

Economy: There are 30 economy seats, so \(\frac{30}{50}=\frac{60}{100}=60\text{%}\) economy seats, which also matches the third pie chart so the answer must be the third chart.
