1.先乘除後加減
所以要先算8230%=820.3(遇到%從個位數網左移兩位為0.30)
820.3=273.333333.......
68+273.3333.....=341.3333.......
答:341.3333........
2.5130%=510.3=170
答:170

1. 先乘除後加減, 所以
68+82÷30%=68+(82÷0.3)=68+273.3333.....=341.33333........
2.
51÷30%=51÷0.3=170

第一題我贊成**和無敵川爺的答案，因為要先乘除後加減喔！除非你的算式是(68+82)÷30%=?，要先把(68+82)算出來，才會是其他兩位的答案！

1.
68+82=150
150÷30%=150 x 100/30=500
2.
51÷30%=51 x 100/30=170
希望可以幫忙到您

1.
先乘除後加減
原式= 68 + 82*10/3 = 341 又 1/3
2
51*10/3 =170
