Hmm not sure about this question. It looks like part of the equation is 98/00 and anything divided by zero is undefined. Maybe the equation is wrong?
What you've given us is called an indeterminate. There is no answer because you've got a term where you are dividing by zero, i.e., 56 98/00. That 98/00 is indeterminate; so the entire problem is also.
56 98/00- 89 99/77= 330177
98/00
(89)56 +89 = 5073
56 + 89 = 145
145
89
0.6292
89 + (23 x 56/7) = 89 + (23 x 8) = 273
56: 2, 7 67: 67 75: 3, 5 81: 3 89: 89
56 + 33 = 89
145.
