Spilt 30 into 10 (30 divided by 10) and then you get 3. The number of males in the class is 3. Now subtract 30 from 3 and you get 27. Therefore, there are 27 females in the class.
I I think this because 1 people that have a phone and a computer are the highest group and two becauseit seems that most of the class has a phone it also seems that most of the class has a computer
