In Martin's class of 20 students, 4 students report that social studies is their favorite class and 75% of the students report that PE is their favorite class. Show your work to explain how to determine whether more students prefer social studies or PE. (5 points)

Answer 1

Answer:

Students like PE more

Step-by-step explanation:

To do this we need to know how much is 75= ? how many kids out of 20 kids

75% the same as = 75/100=3/4=15/20

so 15 out 20 kids like PE

2nd way:4/20 students say S.S. is their favorite

75% say PE is their favorite

you need to get them in the same conditions, one is fraction, and one is percent

4/20= ?%   ? /100  4        __   cross multiply on paper

                           20     100

4x100= 400/20=20

20% say s.s. is their favorite

20% is smaller than 75%

expresson: 4

                 20< 75%

Answer 2

Given: Total number of students = 20

Number of students whose favourite class is social studies = 4

Percentage of students whose favourite class is PE = 75%

To find: Determination whether more students prefer social studies or PE

Solution: The number of students preferring social studies and PE respectively are not given in the same form. So first we need to find out the number of students whose favourite class is PE.

As such, number of students whose favourite class is PE

= 75% of 20

= 75/100 × 20

= 3 × 5

= 15.

We see since 15>4, more number of students prefer PE rather than social studies.
