数学计算题（能简算的要简算）3/1+3/1÷6/54/1÷（6-13/4-13/9）（8/3+6/5+50%）÷4/3

如果你的/代表÷的话
1. 3/1+3/1÷6/5=3+3÷6/5=3(1+6/5)=3*11/5=33/5
2. 原题=4÷（6-13/4-13/9)=4÷[6-13(1/4-1/9)]=4÷(6-5/36)=144
3. 原题=（8/3+6/5+1/2）÷4/3=171/30÷4/3=171/40

1.原式=3+3X5/6
=3+2.5
=5.5
2.原式=4÷（216/36-117/36-52/36）
=4÷【216/36-(117/36+52/36)】
=4÷(216/36-169/36)
=4÷47/36
=4.36/47
=108/47
3.原式=(80/30+36/30+15/30).3/4
=131/30.3/4
=131/40

=3/1+10/3
=6又3分之1
=4/1÷(36/187)
=187/9
=119/30÷4/3
=119/40

你题目写的不太清楚

1/3+1/3÷5/6
=1/3+1/3*6/5
=1/3(1+6/5)
=1/3*11/5
=11/15
1/4÷（6-4/13-9/13）
=1/4÷[6-(4/13+9/13）]
=1/4÷(6-1)
=1/4÷5
=1/4*1/5
=1/20
（3/8+5/6+50%）÷3/4
= （3/8+5/6+1/2）*4/3
=3/8*4/3+5/6*4/3+1/2*4/3
=1/2+10/9+2/3
=1/2+(10+6)/9
=1/2+16/9
=(9+32)/9
=41/9
