The picture shows all the work I did, the reason I took a pic is because it is a little hard to explain by text, but I hope this helped you!
A straight line can be drawn through all the points and the line passes through the point where x=0 and y=0. This best describes a graph of paired points that form a proportional relationship. You can tell this because the line passes directly through the origin (0,0). It also says that it is a straight line that passes through the points, so most likely the line will contain points that have a proportional relationship. Hope that helps :)
A mixed number is in the form x y/z while a improper fraction (76/10) is in the form y/z. We can separate the fraction into two parts. One is 70/10 which = 7 and the other is 6/10 which simplifies to 3/5. So, in order to express 76/10 as a mixed number we must express it as 7 3/5 or 7 6/10. 7 3/5 is equal to 7 6/10.
I hope this helped you!

Hey!
Grape over total: 
After he drinks 1, there will be 1 less. That means it will be over 11
Orange over total: 
Now multiply the fractions

That means the probability is: 
Good luck and hope this helps! :)
