Get fractions in terms of 1/12's
4 2/12 = r + 6 3/12
+4+=+48%2F12
6+=+72%2F12
48%2F12+%2B+2%2F12++=+r+%2B+72%2F12+%2B+3%2F12
50%2F12+=+r+%2B+75%2F12
r+=+50%2F12+-+75%2F12
r+=+-+25%2F12
check answer:
-25%2F12 = -2 1/12
4 2/12 = r + 6 3/12
4 2/12 = -2 1/12 + 6 3/12
4 + 2 - 6 = 3/12 - 1/12 - 2/12
0 = 3/12 - 3/12
0 = 0
OK
