Multiply the recipe by 1%2F2 and add it to the current recipe for 11%2F2
...
broccoli: 11%2F4
11%2F4 = 4*1=4+1=5 so 5%2F4
%285%2F4%29%281%2F2%29+=+5%2F8
5%2F4+%2B+5%2F8+=+%285%2F4%29%282%2F2%29+%2B+5%2F8+=+10%2F8+%2B+5%2F8+=+15%2F8
broccoli: 1 7/8 cups
...
Cooked pasta: 3 3%2F4
13%2F4 = 4*1=4+3=7 so 7%2F4
%287%2F4%29%281%2F2%29+=+7%2F8
7%2F4+%2B+7%2F8+=+%287%2F4%29%282%2F2%29+%2B+7%2F8+=+14%2F8+%2B+7%2F8+=+21%2F8
cooked pasta: 2 5%2F8 cups
...
Salad dressing: 2%2F3
%282%2F3%29%281%2F2%29+=+2%2F6+=+1%2F3
2%2F3+%2B+1%2F3+=+3%2F3+=+1
salad dressing: 1 cups
...
Cheese: 11%2F3
11%2F3 = 3*1=3+1=4 so 4%2F3
%284%2F3%29%281%2F2%29+=+4%2F6
4%2F3+%2B+4%2F6+=+%284%2F3%29%282%2F2%29+%2B+4%2F6+=+8%2F6+%2B+4%2F6+=+12%2F6+=+2
cheese: 2 cups
