Question

at Wally's school, 30% of the students are in 8th grade. If there are 470 students total, find the number of 8th grade students

Answer 1

141 students

Explanation:

We have the equation x=30% · 470

x=0.3 × 470 (Making a percent into a decimal)

x=0.3 ×10 × 47 (Process of making a decimal an integer)

x=3 × 47 (Making a decimal an integer)

x=141 (Solving)

So, there is 141 students in 8th grade.
