Answer:
This is already simplified to the lowest it can go.
Those two numbers dont have the same factors which means 14/45 is its simplest form.
Step-by-step explanation:
14 is only divisible by 1,2,7, and itself
45 is only divisible by 1,5,9,15 and itself so you cant simplify that fraction anymore
9/4 cups
6 3/4 = 27/4
27/4 * 1/3 = 27/12
27/12 = 9/4
7,000 is the answer
