Question

there are 40 students in a class. 9/10 students are present in a day. find the number of absent on that day​

Answer 1

Answer:

absent = 4 students

Step-by-step explanation:

Given that there are 40 students in a class out of which 9/10 present in a day. We need to find out the number of absent students that day.

Number of students present = Total number of students in the class of 9/10

Substitute the known values,

Present students = 40 × 9/10

= 9(4)

= 36

Therefore, there are total 36 students present on that day out of 40.

But we have to find the number of absent students.

So,

Absent students = Total number of students - Present students on that day

Substitute the values,

Absent students = 40 - 36

= 4

Therefore, there were 4 students absent that day.

Answer 2

Given,

There are $40$ students  in a class.

$\frac{9}{10}$ students are present in a day.

W e have to find the the number of students absent on that day

Now,

Number of students present $=$ total number of students $\times$ $\frac{9}{10}$

$= 40\times\frac{9}{10}$

$=36$

The number of students present in the class is $36$

Number of students absent $=$ total number of students $-$ Number of students present

$=40-36$

$=4$

Therefore, the number of students absent on that day is $4$.
