a school has 720 pupils. one day 36 pupils were absent, what fraction represented those who are present?
To find the fraction of pupils who are present, we can subtract the number of absent pupils (36) from the total number of pupils (720) and express it as a fraction.
Number of pupils present = Total number of pupils - Number of absent pupils
Number of pupils present = 720 - 36
Number of pupils present = 684
So, the fraction of pupils who are present is:
Fraction of pupils present = Number of pupils present / Total number of pupils
Fraction of pupils present = 684 / 720
To simplify the fraction, we can divide both the numerator and denominator by their highest common factor, which is 12:
Fraction of pupils present = (684 ÷ 12) / (720 ÷ 12)
Fraction of pupils present = 57 / 60
So, the fraction represented by the pupils present is 57/60 or it can be simplified further as 19/20.
To find the fraction representing the number of pupils who are present, we need to subtract the number of absent pupils from the total number of pupils and express that as a fraction. Here's how to do it:
Step 1: Find the number of pupils who are present.
Total number of pupils = 720
Number of absent pupils = 36
Number of present pupils = Total number of pupils - Number of absent pupils
Number of present pupils = 720 - 36 = 684
Step 2: Express the number of present pupils as a fraction.
Fraction = Number of present pupils / Total number of pupils
Fraction = 684 / 720
Step 3: Simplify the fraction if necessary.
We can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (GCD).
The GCD of 684 and 720 is 12.
684 ÷ 12 = 57
720 ÷ 12 = 60
So, the simplified fraction is 57/60.
Therefore, the fraction representing those who are present is 57/60 or it can be further simplified to 19/20.
36/720 = 1/20 = 5% absent.
So, ...
