Question

Exactly 40% of the sixth-grade students at Roosevelt Middle School take part in after-school activities. There are 60 sixth graders who are taking part in after-school activities. How many sixth graders are at Roosevelt Middle School?

Answer 1

Answer:

150

Step-by-step explanation:

40% of the students take part in after school activities.

The number of 6th graders who take part in after school activities are 60.

Consider the total number of 6th graders as X,

Then 40% of X = 60

(40/100) x X = 60

(2/5) x X =60

X= (60×5) ÷2

= 300 ÷ 2

= 150.

Answer 2

If x is the number of students taking part in after school activities,

Then 40% of x = 60

$\frac{40}{100} \times x = 60 \\ 4x = 600 \\ x = 150$

So there were 150 sixth graders in total at Roosevelt Middle School
