(1/6)*(4.85÷5/18-3.6+6.15*3.6)
=(1/6)*(4.85*3.6-3.6+6.15*3.6)
=(1/6)*3.6(4.85+6.15-1)
=(1/6)*3.6*10
=36/6
=6
{[(5/3)*2+5/2]*8/7-11/5}*5/8
=(10/3+5/2)*(8/7)*(5/8)-(11/5)*(5/8)
=(5/7)*(35/6)-11/8
=25/6-11/8
=100/24-33/24
=67/24
=(1/6)*(4.85*3.6-3.6+6.15*3.6)
=(1/6)*3.6(4.85+6.15-1)
=(1/6)*3.6*10
=36/6
