Answer:
-9/2 = -18/4 = -27/6 = -36/8
= -45/10 = -54/12 = -63/14 = -72/16
= -81/18 = -90/20 = -99/22 = -108/24
= -117/26 = -126/28 = -135/30 = -144/32
= -153/34 = -162/36 = -171/38 = -180/40
= -189/42 = -198/44 = -207/46 = -216/48
= -225/50 = -234/52 = -243/54 = -252/56
= -261/58 = -270/60 = -279/62 = -288/64
= -297/66 = -306/68 = -315/70 = -324/72
= -333/74 = -342/76 = -351/78 = -360/80
= -369/82 = -378/84 = -387/86 = -396/88
= -405/90 = -414/92 = -423/94 = -432/96
= -441/98 = -450/100 = -459/102 = -468/104
= -477/106 = -486/108 = -495/110 = -504/112
= -513/114 = -522/116 = -531/118 = -540/120
= -549/122 = -558/124 = -567/126 = -576/128
= -585/130 = -594/132 = -603/134 = -612/136
= -621/138 = -630/140 = -639/142 = -648/144
= -657/146 = -666/148 = -675/150 = -684/152
= -693/154 = -702/156 = -711/158 = -720/160
= -729/162 = -738/164 = -747/166 = -756/168
= -765/170 = -774/172 = -783/174 = -792/176
= -801/178 = -810/180 = -819/182 = -828/184
= -837/186 = -846/188 = -855/190 = -864/192
= -873/194 = -882/196 = -891/198 = -900/200
those are all that is equivalent to 4^⋅ 4^-8
