54% of the pupils in a class are girls. what % of pupils are boys? if the number of boys are 23. find the strength of the class.
To find the percentage of boys in the class, we need to subtract the percentage of girls from 100%. Since the percentage of girls is 54%, we can subtract this from 100% to find the percentage of boys:
100% - 54% = 46%
Therefore, 46% of the pupils in the class are boys.
Next, we are given that the number of boys is 23. We can use this information to find the total number of pupils in the class.
Let's assume the total number of pupils in the class is 'x'.
Since 46% of the pupils are boys, we can express this as a proportion:
46/100 = 23/x
To solve for 'x', we can cross multiply:
46x = 2300
Divide both sides of the equation by 46 to isolate 'x':
x = 2300 / 46
Performing the division, we find that:
x = 50
Therefore, the total strength of the class is 50.
well, 100% is all of the students.
what is 100-54?
no idea what the "strength" of a class is. Size?
If so, then 23 = (1-.54)x
