The total number of students in the 6th grade is 300.
What is a percentage?
A percentage is a number or ratio expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100.
For the given situation,
25% of the 6th-grade class students is 75
Let x be the total number of students, say 100%.
⇒ [tex]25\%=\frac{1}{4}[/tex]
Here, 1 part is 25% then 4 parts are 100%
Thus 1 part = 75, then
⇒ [tex]4 parts = 4(75)[/tex]
⇒ [tex]4 parts = 300[/tex]
Hence we can conclude that the total number of students in the 6th grade is 300.
