Answer:
Number of students who uses pencils = 64 students
Explanation:
Pens : pencils = 3 : 2
Pen = 3
Pencil = 2
Total = 3 + 2 = 5
If there is a total of 160 middles school students how many of them used pencils?
Number of students who uses pencils = ratio of pencil / Total × number of students
= 2 / 5 × 160
= (2 * 160) / 5
= 320/5
= 64
Number of students who uses pencils = 64 students
Number of students who uses pen = ratio of pen / Total × number of students
= 3/5 × 160
= (3*160)/5
= 480/5
= 96 students
