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

Answer:

141 students

Step-by-step 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.
