Answer:

  • 42 students; (28 students); 70 students
  • (60%); 40%; (100%)

Explanation:

The percentages total 100%, so the missing percentage is

100% - 60% = 40%

The numbers on the number lines are proportional, so now you can write ...

?/100% = 28/40% . . . . . . ? total students

Multiplying by 100% gives ...

? = 28/0.4 = 70 . . . . . total students

Then the 60% portion of students can be found two ways:

60% × 70 = 42 students . . . . 60% of students

70 -28 = 42 students
