However, when I went to Algebra.help they did the problem by converting the mixed problem to an improper fraction and then worked it that way.

However, I know that the answers should be the same.

Please check my method. I don't want to convert the whole numbers to mixed.

9 10/12 minus 5 6/7

9 70/84 minus 5 72/84

equals 4 2/84

reduced to 4 1/42

Algebra help say the answer is:

3 41/42

**Ms. Sue**, Monday, December 20, 2010 at 3:08pmYour algebra help is correct.

Your problem is in your second step. You can't take 72 from 70. Therefore, you need to change 9 70/84 to 8 154/84.

8 154/84 - 5 72/84 = 3 82/84 = 3 41/42
