Ron ate pizza with his friends the other day. If they ordered a 12-slice pizza and each of them ate 4 slices, how many friends were there with Ron?
Let the number of friends that ate with Ron be represented by F. That means the total amount of people that ate that day were 1 + F
If each of them ate 4 slices, and the pizza only has 12 slices, that means there could only have been 12/4 = 3 people eating
If the total number of people eating was 3, and if was also represented by 1+F then we have 3 = 1+ F
Solving for F we have 3-1 = F
F = <<2=2>>2 friends ate with Ron
