分数简算 3/4乘以16= 12除以3/5= 0.3乘以5/6= 1除以7/8=
5/7乘以2/3除以5/7 1/2乘以1/3除以1/2乘以1/3 0乘以7/12+1/8 48乘以（7/12+1/3）除以2/3 23-8/9乘以3/4除以1/27 5除以[（2/3+1/5）乘以1/13]

3/4乘以16
=3×4
=12;
12除以3/5
=12×5/3;
=4×5
=20;
0.3乘以5/6
=0.05×5
=0.25;
1除以7/8
=1×8/7
=8/7;
5/7乘以2/3除以5/7
=5/7×2/3×7/5
=2/3;
1/2乘以1/3除以1/2乘以1/3
=1/2×1/3×2×1/3
=1/9;
0乘以7/12+1/8
=0+1/8
=1/8;
48乘以（7/12+1/3）除以2/3
=(4×7+16)×3/2
=44×3/2
=66;
23-8/9乘以3/4除以1/27
=23-8/9×3/4×27
=23-18
=5;
5除以[（2/3+1/5）乘以1/13]
=5÷[(10/15+3/15)×1/13]
=5×13×15/13
=5×15
=75;
