A good way to see what Shelby first did is to turn the amount she says she made into an improper fraction. You do this by multiplying the number to the left of the fraction by the denominator and adding it to the top. This shows Shelby divided 7 by 4 to get her 1 3/4 cups of juice answer. Since Shelby divided, a good option would be to try and multiply the original 7 amount by 4, as there is also 4 cups in a single quart, so 7 times 4. This number will be how many cups of juice she made.
