Answer: 280</h3>
Work Shown:
x = number of students in the 6th grade class
30% = 30/100 = 0.30
30% of x = 0.30x this is equal to 84 since "30% of the 6th graders are boys (and there are 84 boys in sixth grade)", so we say 0.30x = 84
Divide both sides by 0.30 to isolate x
0.30x = 84
0.30x/0.30 = 84/0.30
x = 280
So there are 280 students overall in the 6th grade class.
Answer:
280 students
Step-by-step explanation:
84 is 30% of a whole. In order to find the whole we must divide.
to divide we have to turn 30% into a decimal (move the point two spaces to the left: 0.3) then 84/0.3 and that gives you 280.
and to check your answer, if you do 280*0.3 that gives you 84.
so, 84 is 30% of the whole 280
there are 280 students.
Hope this helps!
