3/4÷(6/5%1/2)+3/4 = 简便算法

3/4÷(3/4÷2/5)+1/2 =3/4÷3/4*2/5+1/2 =1*2/5+1/2 =2/5+1/2 =9/10你好,本题已解答,如果满意 请点右下角“采纳答案”.

3/4÷6/5+3/4÷6 =3/4*5/6+3/4*1/6 =3/4*5/6+1/6 =3/4*1 =3/42又1/4÷10÷5/9 =9/4÷10*9/5 =9/4÷18 =9/4*1/18 =1/8,这道不简算

1/(2/3)/(3/4)/(4/5)/(5/6) =1÷(2/3)÷(3/4)÷(4/5)÷(5/6)=1 * 3/2 * 4/3 * 5/4 * 6/5=1*6/2=3

你好!3/4+3/5÷6/5 =3/4+3/5*5/6 =3/4+1/2 =3/4+2/4 =5/4 如有疑问,请追问.

你确定全是除号??全是除号的话这样1/(2/3)/(3/4)/(4/5)/(5/6)=(3/2)*(4/3)*(5/4)*(6/5)相消后=3

把除改成乘,约分后为3

2/3*【(3/4-1/6)÷1/5】=2/3*【(3/4-1/6)*5】=(1/2-1/9)*5=7/18*5=35/18

3÷4+5÷6-3÷4+1÷6=1.0000000000000002计算结果就是这样的

=4/3x6+6x3/4= 8+9/2=12又1/2

1÷(2÷3)÷(3÷4)÷(4÷5)÷(5÷6)=1÷2*3÷3*4÷4*5÷5*6=1*6÷23÷34÷45÷5=1*3*1*1*1=3
