You can put this solution on YOUR website! Write this as an equation, where "what" means the unknown, which is x:
75% of what is 1.25
.75 * x = 1.25
So to find x, divide both sides by .75
Check it just to be sure I didn't embarrass myself (again!) to the whole world by making a dumb error:
75% of 5/3 is 1.25 True or false? True! It checks!!
