There are 28 students in zacks class.one forth are absent how many students are present? Answer choises a.16 b.7 c.9 d.21

1 - 1/4 = 3/4

3/4 of 20 = ?

3/4 of 28 = ?

21

To find the number of students present, we need to calculate three-fourths of the total number of students. Here's how to do it:

1. Determine how many students are absent. According to the question, one-fourth of the total students are absent. To find this, multiply the total number of students by one-fourth:
Absent students = 28 * 1/4 = 7

2. Subtract the number of absent students from the total number of students to find the number of students present:
Present students = Total students - Absent students = 28 - 7 = 21

Therefore, there are 21 students present in Zack's class. So, the correct answer is d. 21.
