Question

William has a 22 ounce coffee. He drinks 2 ounces. Enter the percentage of ounces William has left of his coffee. Round your answer to the nearest hundredth.

Answer 1

Answer:

Therefore, we conclude that William left 90.9% of an ounce of his coffee.

Step-by-step explanation:

We know that William has a 22 ounce coffee. He drinks 2 ounces. We calculate percentage of ounces William has left of his coffee.  

We get 22-2=20 ounce coffee.

We have the following proportion:

$22:100\%=20:x\%\\\\22x=20\cdot 100\\\\x=\frac{2000}{22}\\\\x=90.9\%$

Therefore, we conclude that William left 90.9% of an ounce of his coffee.
