TOTAL GROUP= 3
GROUP OF THREE REPORT PICTURE=9
TOTAL STUDENT USED PICTURE=585
TOTAL STUDENTS= ?
3 GROUP OF STUDENTS= 585/3
= 195
THEREFORE TOTAL NUMBER OF STUDENTS= 195.
Answer:
195 students were there in all.
Step-by-step explanation:
(Listing some basic informations from the question)
1 group = 3 students
1 report = 9 pictures
So, total pictures were => 585 pictures
Let the unknown number of student be x.
According to the statement the equation will be,
x/3 (9) =585 (Do cross multiplacation of x/3 (9). )
x/1 (3) = 585 (After cross multiplacation this is what we get.)
3x=585 (we get 3x by multiplying x/1 (3).)
x= 585/3 ( Divide 585/3)
x= 195 (ans)
Answer: There were 195 students in all.
