简便计算10道

5/9+11/15-4/9+4/15
=(5/9-4/9)+(11/15+4/15)
=1/9+1
=1又1/9
3/5×6.75+4.25×60%+0.6
=0.6*(6.75+4.25+1)
=0.6*12
=7.2
1.375×95+4×1.375+1.375
=1.375*(95+4+1)
=1.375*100
=137.5
（3/4-1/2）÷3/4
=3/4 ÷3/4-1/2÷3/4
=1-2/3
=1/3
12×3/8÷12×3/8
=12÷12×3/8×3/8
=3/8×3/8
9/64
（18-3/7）÷9/7
=18÷9/7-3/7）÷9/7
=14-1/3
=13又2/3
1又3/4-3/4×2/3
=1+3/4-3/4×2/3
=1+3/4×（1-2/3）
=1+3/4×1/3
=1+1/4
=1又1/4
3/8+5/8×4/15
2/9+1/2÷4/5+3/8
2-6/13÷9/26-2/3哥，我就是最后4个不会写，您偏偏给落下了……3/8+5/8×4/15 =3/8+1/6=9/24+4/24=13/242/9+1/2÷4/5+3/8=2/9+1/2×5/4+3/8=2/9+ 5/8+3/8=2/9+1=1又2/92-6/13÷9/26-2/3=2-6/13×26/9-2/3=2- 4/3-2/3=2-(4/3+2/3)=2-2=0
