Q. Teachers divided students into groups of 3. Each group of 3 wrote a report that had 9 pictures in it. The students used 585 pictures altogether. How many students were there in all?
Calculate Number of Groups: We need to find out how many groups of 3 students there were if each group used 9 pictures and altogether 585 pictures were used. To do this, we first find out how many groups there were by dividing the total number of pictures by the number of pictures each group used.Calculation: 585÷9
Find Total Students: Now we perform the division to find out the number of groups. 585÷9=65 This means there were 65 groups of students.
Perform Division: Since each group consists of 3 students, we multiply the number of groups by 3 to find the total number of students.Calculation: 65×3
Perform Multiplication: Now we perform the multiplication to find the total number of students.65×3=195This means there were 195 students in total.
