To calculate 50/((1/2)-(3/4)+(4/5)), Beibei's method is the original formula=50/(1/2)-50/(3/4)+50/( 4/5); and Jingjing's method is to find the reciprocal of the original formula = ((1/2)-(3/4)+(4/5))/50; Whose calculation method is wrong? Who's calculation method is correct?
计算50/((1/2)-(3/4)+(4/5))，贝贝的方法是原式=50/(1/2)-50/(3/4)+50/(4/5)；而晶晶的方法是求原式的倒数=((1/2)-(3/4)+(4/5))/50；问谁的计算方法错误？谁的计算方法正确？
