In a class 42 pupils, 4 boys and 3 girls are absent. What fraction of the pupils is present?
The number of pupils present can be calculated by subtracting the number of absent pupils from the total number of pupils: 42 - 4 - 3 = 35.
Therefore, the fraction of pupils present is 35/42.
To find the fraction of pupils that are present, we need to subtract the number of absent pupils from the total number of pupils.
Total number of pupils = 42
Number of absent pupils = 4 boys + 3 girls = 7
Number of students present = Total number of pupils - Number of absent pupils
= 42 - 7
= 35
Therefore, the fraction of pupils present can be expressed as:
Number of pupils present / Total number of pupils
35 / 42
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor (GCD), which in this case is 7:
35 ÷ 7 / 42 ÷ 7
5 / 6
So, the fraction of pupils that are present is 5/6.
To find the fraction of pupils present, we need to determine the number of pupils who are present and divide it by the total number of pupils in the class.
To find the number of pupils present, we subtract the number of absent pupils (boys and girls) from the total number of pupils in the class.
Total number of pupils = 42
Number of boys absent = 4
Number of girls absent = 3
Number of pupils present = Total number of pupils - Number of absent pupils
Number of pupils present = 42 - (4 + 3)
Number of pupils present = 42 - 7
Number of pupils present = 35
Now let's calculate the fraction of pupils present by dividing the number of pupils present by the total number of pupils in the class.
Fraction of pupils present = Number of pupils present / Total number of pupils
Fraction of pupils present = 35 / 42
To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 7.
Fraction of pupils present = (35 / 7) / (42 / 7)
Fraction of pupils present = 5 / 6
Therefore, the fraction of pupils present in the class is 5/6.
