Question

Sergio and Allen ate lunch together in the school cafeteria. Each boy ordered a cheeseburger with fries. Sergio only ate 1/7 of his cheeseburger, while Allen ate 3/7 of his cheeseburger. How much cheeseburger did they eat together?

Answer 1

4/7

Explanation:

The word together symbolizes that we are adding.

We add the numerators but keep the denominator the same since it is already the same.

1+3 is 4, so that is our new numerator.

1 3 4

__ + __ = __

7 7 7

Hope this helps!

Answer 2

it's pretty easy to add considering the denominators are the same number. technically in this problem it's 3+1 and then add the denominator which is 7. this makes the answer 4/7
