Alrighty then sir!
These questions usually require quite a bit of thinking, but this is quite easy, so we'll slide with this!
Now, 4 cups are equal to 1 quart, and that's important!
In total, for number 7, Benji ate the amount that the question describes!
Remember, 4 cups are equal to 1 quart
4 x 7 = 28 / 2 = 14 pints / 2= 7 quarts for Number 8
Number 9
1 + 5 = 6: Keep the equation for now!
4 + 8 = 12! Keep that too
12 + 6 = 18 cups.
We have to minimize this
16 cups are 1 gallon
18 - 16 = 2
A is your answer for No.9!
Hope this helps!
