Question

On Thursday, Abram asked several students to make their favorite class. He found 32% of the students liked science class best and another 1/2 of the students liked social studies class best. What fraction of the students liked either science or social studies classes best?

A. 41/50 B. 5/32
C. 1/16 D. 27/32

Answer 1

To find the fraction of students who liked either science or social studies classes best, we need to add the fractions that represent the students who liked each class individually.

32% of the students liked science class best, which is equivalent to 32/100 = 8/25.

1/2 of the students liked social studies class best.

To find the fraction representing the total number of students who liked either science or social studies classes best, we add the fractions representing each class:

8/25 + 1/2 = (8/25) + (13/25) = 21/25.

Thus, the fraction of students who liked either science or social studies classes best is 21/25, which is equivalent to answer choice A. So, the correct answer is A.
