Question

35% of the students at charles drew middle school are 6th graders if there are 84 sixth graders what is the total number of student in the school

Answer 1

Answer: The total number of student in the school  = 240.

Step-by-step explanation:

Let x be the total number of students in the school.

Given: 35% of the students at Charles drew middle school are 6th graders.

i.e. Number of sixth graders = 35% of x = 0.35x   [35% = 0.35]

Since there are 84 sixth graders in the school,

So  $0.35x=84$

Divide both sides by 0.35, we get

$x=\dfrac{84}{0.35}=\dfrac{84\times100}{35}=240$

Hence, the total number of student in the school  = 240.
