0/2=0 because anything divided by zero is zero.
6 goes into 516 86times.You only divide 516/6
1, 3, 5 are functions because they pass the vertical line test
You would change the denominator and get the lowest common denominator. Thos would be 30. You would do 11/6 x 5/5 = 55/30. Then do 3/5 x 6/6 = 18/30. Then add 55/30 + 18/30 = 73/30 and simplify.
