Answer:

75 students

Step-by-step explanation:

first write a ratio of the students asked to students dislike

40:30, 40 to 30, or 40/30

now simplify the ratio

4/3

now she asked 40 students, so we have to find out the unit rate

so we have to flip the fraction to 3/4 and then divided the top and bottom by 4

0.75/1

now multiply the top and bottom by 100

75/100
