Tracy has 7/8 pounds of butter in her refrigirator. She uses 2/3 of it for cookie batter. How much of the butter did she use?

16/24

Step-by-step explanation:

So you need to get a common denominator before you try to answer the whole question. Turn the denominator into 24. Since you would multiply 8 by 3, multiply the 7 by 3. That would make 21/24. Make the 3 a 24, multiplying it by 8 and doing the same to the 2 making 16/24.
