这里有20道你自己慢慢选！

Answer 3

（3又3/4-90.2+ 1/3 ）×4.5÷（7.05+6又9/20)
=（3又3/4-90.2+ 1/3 ）×4.5÷13.5

=5/4-30-1/15+1/9
=5/4-30+2/45
=233/180-30
=-28又127/180

[(1/3+4.8÷1又3/5）-2又2/3]×1又二分之一
=(1/3+4.8÷1又3/5)×1又二分之一 - 2又2/3×1又二分之一
=1/3×1又二分之一+4.8÷1又3/5×1又二分之一-2
=1/2+9/2-2
=3

[4/7×(3/5-0.25)+3/10]÷1/2
=[4/7×3/5-4/7×1/4]÷1/2+3/10÷1/2
=(12/35-1/7)÷1/2+3/5
=1/5÷1/2+3/5
