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