Question

Which expression does not belong? Be prepared to explain your reasoning.

Answer 1

Answer:

Your answer will be the third one.

Step-by-step explanation:

If you add up the numbers on top for the first, secnd, and fourth ones and divide that by the number ont he bottom, you will constantly get 6. However, for the third one, you'll get seven since 9+9 is 18 and 5+5 is 10. Add that up and you get 28, and divide that by 4 and you get 7, not 6. hope this helps!

Answer 2

Answer: (9+9+5+5)/4

Step-by-step explanation:

Because if you add all of the numbers on the numerator and divide by the denominator, all of them equal 6 except that one. So it doesn't belong
