Answer:
6 2/3.
Explanation:
Since 1/10 of the box is equal to 2/3 all we need to do is multiply 2/3 by 10. Or add 2/3 to itself 10 times if that makes it easier for you.
2/3 x 10 = 6 2/3
(since I didn't convert 10 into a fraction by making it 10/1 it came out as a decimal. "6.66666666667 ." Which when converted to a fraction makes it 6 2/3. In case you were confused if you used a calculator for just "2/3 x 10".)
6 2/3 is your answer.
Hope this helps and have a nice day!
