8x/9除以(x+1)=6分之7 解要有过程,要详细

如果题目是(1.6x+5)/8x=7/9 那么 7*8x=9*(1.6x+5) 56x=14.4x+45 56x-14.4x=45 41.6x=45 x=45/41.6=1.08

9.6x-8x=7.2 1.6x=7.2 x=7.2/1.6 x=4.5

8/9x=1/6+16/51 解:8/9x=17/102+32/102 8/9x=49/102 x=49/102*9/8 x=147/272

48/X=72 72X=48 X=0.67 除不尽

8x(8/9-1/2-1/6) =8x(16/18-9/18-3/18) =8x2/9 =16/9 =1又7/9

1/3

48x27/49 =(49-1)×27/49 =49×27/49-27/49 =27-27/49 =26又22/49 9×(1/9+1/7)x7 =9×1/9×7+9×1/7×7 =7+9 =16 7/8+7/8x99 =7/8×(1+99) =7/8×100 =7/2 ×25 =175/2 5/9x1/8X27 =5/9×27 ×1/8 =15×1/8 =15/8
