Answer 2

Sure, I can help you with that math problem. To solve the expression:

9 2/21 + 6 5/21 - 7 13/21

First, let's convert the mixed numbers into improper fractions:

9 2/21 = (9 * 21 + 2)/21 = 191/21 6 5/21 = (6 * 21 + 5)/21 = 131/21 7 13/21 = (7 * 21 + 13)/21 = 160/21

Now we can perform the addition and subtraction:

191/21 + 131/21 - 160/21

To add or subtract fractions, we need a common denominator. In this case, the denominators are already the same, so we can combine the numerators directly:

(191 + 131 - 160)/21 = 162/21

Now we can simplify the fraction:

162/21 = 54/7

Therefore, the result of the expression 9 2/21 + 6 5/21 - 7 13/21 is 54/7.
