Wow...interesting way of doing it. Guess i donit the old way:
4 3/4 + 2 5/6
4x4+3=19/4
2x6+5=17/6
Change both denominators to 12 and multiply top by hoe many times the denominator goes into the LCD
57/12 + 34/12 = 91/12
12 goes into 91
7times with a remainder of 7/12
So 7 7/12
Your way is WAY faster and easier
