Question

If 3 students are absent from class of 48. a)what fraction of the class in absent. b)what fraction of the class in present

Answer 1

Answer:

$total \: students = 48 \\ b) \: \: number \: of \: students \: present = 48 - 3 = 45 \\ fraction = > \: \: \frac{present\: student}{total \: student} \\ = \frac{45}{48} = \frac{15}{16}$

$a) \: number \: of \: student \: absent \: = 3 \\ fraction = > \frac{3}{48} = \frac{1}{16}$

Answer 2

Answer:

Absent = 1/16.

Present= 15/16.

Step-by-step explanation:

• GIVEN : 3 Students are absent
• Total number of students is 48.
• Number of students present = 48-3= 45.

as we know the formula = (number of events) / (total number of events).

so fraction of ABSENT = 3/48= 1/16.

and fraction of PRESENT= 45/48= 15/16.
