解:1、(2X/3)/36=1/3; 2X=36; X=18;
2、0.4+0.2X=5; X=23;
3、1/4*(4.8-0.01*8)=1.18.
2、0.4+0.2X=5; X=23;
3、1/4*(4.8-0.01*8)=1.18.

2/3X÷36 = 1/3
2/3X = 1/3×36
2/3X = 12
X =12×3/2
X=18
2/5+20%X = 5
1/5X = 5-2/5
X = (5-2/5)×5
X= 25-2
X = 23
1/4×(8×60% - 1%÷1/8)
=1/4×(8×3/5 - 1/100×8)
=1/4×8×3/5- 1/4×1/100×8
=6/5 - 1/50
