the 9/10 student of class 5 was absent and only 3 were present . How many students are there in class 5
⋅
To find out the total number of students in class 5, you need to use the information that 9/10 of the students were absent and only 3 were present.
First, you need to determine how many students were present by dividing the number of present students (3) by the fraction of students present (1/10). This can be done by multiplying 3 by the reciprocal of 1/10, which is 10/1, resulting in 3 * 10 = 30 students present.
Since 9/10 of the students were absent, you can find the total number of students by dividing the number of present students (30) by the fraction of students present (1/10) and multiplying it by 10/9, the reciprocal of 9/10. This can be calculated as 30 * (10/1) * (1/9) = 300/9 = 33 and 1/3.
Therefore, there are approximately 33 students in class 5.
Whole class have 10 / 10 students.
9 / 10 student was absen.
3 students were present.
3 students = 10 / 10 - 9 / 10 = 1 / 10
1 / 10 = 3 students
Solve this.
