Its either 3 or 2
the third way matches only if there's another reference line
I'll go with 3
2 because you make them with the same denominators that both go into each other EX: 8x9=72 7/8 now equals 63/72 and 4/9 now equals 28/72 now add them together 63/72 + 28/72= 91/72= 1 19/72
Estimation :
20/0.05 = 400
