解方程 x+(4/3-1/8)=5/12 x+29/24=5/12 x=5/12-29/24 x=-19/24

解方程 (1) x+3/10=1又2/3 x=1又2/3-3/10 x=1又11/30 (2)x-3/8=1又5/12 x=1又5/12+3/8 x=1又19/24

解:(1)7x﹣5x=4+8,2x=12,x=6;(2)4(3x﹣2)+40=5(x+6),12x﹣8+40=5x+30,7x=﹣2,x=﹣ .

1/2×5/8×2/5 =5/16×2/5 =1/8 4×1/4÷3/2 =1×2/3 =2/3 5/12÷3/4÷5/6 =5/9×6/5 =2/3 5/6÷5/6×6/7 =1×6/7 =6/7
