4分之3÷5分之6+4分之3x6分之7%4分之1

3/4÷6/5+3/4×7/6-1/4 =3/4×5/6+3/4×7/6-1/4 =3/4×(5/6+7/6)-1/4 =3/4×2-1/4 =3/2-1/4 =6/4-1/4 =5/4

3/5X5/6-3x=1/5 1/2-3x=1/5 5-30x=2 x=0.1 ~希望对你有帮助,请及时点击【采纳为满意回答】按钮~ ~手机提问的朋友在客户端右上角评价点【满意】即可~ ~你的采纳是我前进的动力~~

(7+5分之7)x14分之5 =7×5/14+7/5×5/14 =2.5+0.5 =3 (6分之5-4分之1x3分之2)÷6分之1 =(5/6-1/6)÷1/6 =2/3÷1/6 =4 1.75×7分之6+14分之3x4分之7+4分之7 =7/4×(6/7+3/14+1) =7/4×29/14 =29/8 (8分之5-4分之1)÷(9分之8+3分之1) =3/8÷11/9 =27/88

5/9÷x=10/11 5/9=10/11x x=11/18 1+3/4x=2 3/4x=1 x=4/3 (x-6)*5/6=25 x-6=30 x=36 (3/4+2/3)x=17/24 17/12x=17/24 x=1/2 5x-3*7/10=7/5 5x=7/5+21/10 5x=14/10+21/10 5x=35/10 x=7/10 4/5+1/2x=9/10 8+5x=9 5x=1 x=1/5 3/4x+1/4=1/2 3/4x=1/2-1...

(1) 8分之3x+4分之1x=8分之3 (3/8)x +(1/4)x =3/8 (5/8)x= 3/8 x= 3/5 (2) 5分之4x÷4分之3=16 (4/5)x/(3/4) = 16 (4/5)x = 12 x=15 (3) 0.6:0.45=x分之12 0.6/0.45=12/x 60/45=12/x 60x=540 x=9 (4) 2.5+2又2分之1x=3又3分之1 5/2 + (5/2)x = 1...

4分之3x减12分5=6分之5 解:3/4x=5/6+5/12 3/4x=5/4 x=5/4÷3/4 x=5/3

2分之1÷(3-6分之5x3) =1/2÷(3-2.5) =1/2÷0.5 =1 (18x3分之1+27÷4分之3)÷12 =(6+36)÷12 =42÷12 =3.5 4分之3x5分之2+5分之2÷1又3分之1 =3/20+3/20 =3/10

(-1)的n+1次方乘以(n+1)分之nx的n次方 观察:可知分母是n+1,分子的系数是n,x的次方和第几项是一样的,而正负号则是正负交替,因此用(-1)的n+1次方就可以了,所以是(-1)的n+1次方乘以(n+1)分之nx的n次方
