18. 45% of the students at River
Middle School walk to school. If
234 students walk to school, how
many students are at River Middle
School altogether?

Step-by-step explanation:

From the above question, 45% of students walk to school and the 45% in number is 234.

Total number of students will be:

45% = 234

100% = ×

Therefore 100% x 234 = 45%x

Convert the % to numbers by dividing through by 100

= 1 x 234= 0.45x

= 234/0.45 = x

=520 = x
