Answer:

8

Step-by-step explanation:

When rounding to the nearest 10:

  • If the units are 0, 1, 2, 3 or 4 → round down
  • If the units are 5, 6, 7, 8 or 9 → round up

Therefore:

164 rounded to the nearest 10 = 160

18 rounded to the nearest 10 = 20

To approximate the number of students in each year group, divide the rounded number of students by the rounded number of groups:

⇒ 160 ÷ 20 = 8
