Right Hand Side:215
⟹Left Hand Side=Right Hand Side
∴Statement A is true.
For statement B, we have:
Left Hand Side:57×1120=5×17×120=5840
Right Hand Side:57=5×1207×120=600840
5840<600840
⟹Left Hand Side<Right Hand Side
∴Statement B is true.
For statement C, we have:
Left Hand Side:45×1120=4×15×120=4600
Right Hand Side:45
