【(4/5+3.6)/(5/6)】*(6.1+2/5)
=(0.8+3.6)*6/5*(6.1+0.4)
=4.4*1.2*6.5
=4.4*7.8
=4*7.8+0.4*7.8
=31.2+3.12
=34.32
=(0.8+3.6)*6/5*(6.1+0.4)
=4.4*1.2*6.5
=4.4*7.8
=4*7.8+0.4*7.8
=31.2+3.12

【(4/5+3.6)/(5/6)】*(6.1+2/5)
=【(0.8+3.6)×(6/5)】*(6.1+0.4)
=【(0.8+3.6)×1.2】*(6.1+0.4)
=(4.4×1.2)*6.5
=1.32×4*6.5
=1.32×26
=34.32
=【(0.8+3.6)×(6/5)】*(6.1+0.4)
=【(0.8+3.6)×1.2】*(6.1+0.4)
=(4.4×1.2)*6.5
=1.32×4*6.5
=1.32×26
=34.32
