1. Perry surveyed 60 students at her school.

=> 0.45 of the students said that their favorite subject is math

=> 0.45 x 100 = 45%

Thus, 45 % of 60:

=> 60 *.45 = 27

35% of the student said their favorite is science:

=> 35% / 100 = 0.35

=> 35% 0f 60 equals:

=> 60 *.35 = 21

Thus, 27 - 21 = 6 of the student said that they love math over science.
