Question

A recent survey found that 7 out of 9 students eat lunch once a week. If 450 students were surveyed, how many eat school lunch at least once a week

Answer 1

To do this, set this up like a fraction and solve for x 

7/9 = x/450 
(7/9) x 450 = x 
x= 350 students 

This is like finding an equivalent fraction for 7/9 :) hope this helps!
