SO WE MEET AGAIN MY FRIEND. The answer is 10 2/7
To explain this, add the cups of popcorn with the cups of pretzels, so you get 6 3/4 + 2 1/4, and all that equals to 9, because 6+2=8, and with the 3/4+1/4, 3+1=4, 4/4=1. Then, you divide it by the snack bags she put them in, which is 7/8 cups in each. So you divide 9 with 7/8. 9/1 divided by 7/8, then you invert it to turn the division to multiplication, 9/1 • 8/7, which equals to 72/7, which simplifies to 10 2/7
