in a class of 36 pupils, 12 are girls. what fraction of the class are boys
if the rest are boys there are 36 - 12 = 24 boys
so 24/36 = 2/3
Well, if there are 12 girls in a class of 36 pupils, then the number of boys would be 36 minus 12, which is 24. So, the fraction of the class that are boys would be 24/36, which can be simplified to 2/3. Those boys have quite the fraction-tastic party going on!
To find the fraction of the class that are boys, you need to subtract the number of girls from the total number of students and then express the result as a fraction.
Total Number of Students = 36
Number of Girls = 12
Number of Boys = Total Number of Students - Number of Girls
Number of Boys = 36 - 12
Number of Boys = 24
So, there are 24 boys in the class.
To find the fraction of boys, you can express it as a fraction:
Fraction of Boys = Number of Boys / Total Number of Students
= 24 / 36
= 2/3
Therefore, two-thirds of the class are boys.
To find the fraction of the class that are boys, we need to subtract the number of girls from the total number of pupils and then express the result as a fraction.
Total number of pupils = 36
Number of girls = 12
Number of boys = Total number of pupils - Number of girls
= 36 - 12
= 24
Therefore, there are 24 boys in the class.
To find the fraction of the class that are boys, we divide the number of boys by the total number of pupils:
Fraction of boys = Number of boys / Total number of pupils
= 24 / 36
Now, to simplify this fraction, we find the greatest common divisor (GCD) of 24 and 36, which is 12:
24 / 36 = (24 ÷ 12) / (36 ÷ 12) = 2/3
So, the fraction of the class that are boys is 2/3.
