1/4*(4.85÷5/18-3.6+6.15*3又3/5)+(5.5-4又1/2)1/4*(4.85÷5/18-3.6+6.15*3又3/5)+(5.5-4又1/2)1/4*(4.85÷5/18-3

1/4*(4.85÷5/18-3.6+6.15*3又3/5)+(5.5-4又1/2)
1/4*(4.85÷5/18-3.6+6.15*3又3/5)+(5.5-4又1/2)

1/4*(4.85÷5/18-3.6+6.15*3又3/5)+(5.5-4又1/2)
1/4*(4.85÷5/18-3.6+6.15*3又3/5)+(5.5-4又1/2)
=(4.85×18/5-18/5+6.15×18/5)/4+(5.5-4.5)
=[(4.85+6.15-1)×18/5]/4+1
=10×18/5÷4+1
=36÷4+1
=9+1
=10
