Answer: 6 and 1/12 cups
Step-by-step explanation:
For this problem, we add 3 and 2/3 + 1 and 3/4 + 2/3. We can change these mixed numbers into improper fractions to make the math easier:
11/3 + 7/4 + 2/3
Next, we can add the 11/3 and 2/3 since they have the same denominator (bottom number). This gives us 13/3.
13/3 + 7/4
Now that we have two fractions, we just add them together. This leaves us with 6 and 1/2.
If you're having trouble with adding fractions with denominators that aren't the same, here are some videos (if you can't click the link, just copy and paste into the search bar):

That is 62x9 which is 9x2=18 and 9x60=540 so you then add 540+18=558 chairs
30-f+8f=30
30+7f=30
Move +30 to the right side. Sign changes from +30 to -30.
30-30+7f=30-30
7f=0
Divde by 7
7f/7=0/7
Cross out 7 and 7, divide by 7. Becomes 1*1*f=f
f=0
Answer: f=0
