Starting with
1%2F3 + 3 2%2F3 + 9 7%2F12
...
Convert the mixed fraction to improper fractions
*multiply the denominator by the whole number, then add the numerator. Put the result over the denominator.
32%2F3 = 3*3=9+2=11 so 11%2F3
97%2F12 = 12*9=108+7=115 so 115%2F12
...
1%2F3+%2B+11%2F3+%2B+115%2F12
Establish common denominators
%281%2F3%29%284%2F4%29+%2B+%2811%2F3%29%284%2F4%29+%2B+%28115%2F12%29
4%2F12+%2B+44%2F12+%2B+115%2F12
...
Add the numerators
163%2F12
...
Revert back to a mixed number. How many times does 12 go into 163 evenly? This is the whole number. How much was left over? That is the numerator.
