能简算的要简算(3/5+2.4/2/3)/0.71/10*1/8+4/5*1/8+1/80(8/15-9/20)/(3/4+1/8)[4/5+(2/7-2/7)*7/8]/4/5能简算的要简算(3/5

能简算的要简算(3/5+2.4/2/3)/0.71/10*1/8+4/5*1/8+1/80(8/15-9/20)/(3/4+1/8)[4/5+(2/7-2/7)*7/8]/4/5
能简算的要简算
(3/5+2.4/2/3)/0.7
1/10*1/8+4/5*1/8+1/80
(8/15-9/20)/(3/4+1/8)
[4/5+(2/7-2/7)*7/8]/4/5

能简算的要简算(3/5+2.4/2/3)/0.71/10*1/8+4/5*1/8+1/80(8/15-9/20)/(3/4+1/8)[4/5+(2/7-2/7)*7/8]/4/5
(3/5+2.4/2/3)/0.7
=(0.6+3.6)÷0.7
=4.2÷0.7
=6
1/10*1/8+4/5*1/8+1/80
=1/80+8x1/80+1/80
=1/80x(1+8+1)
=1/80x10
=1/8
(8/15-9/20)/(3/4+1/8)
=1/12÷7/8
=2/21
[4/5+(2/7-2/7)*7/8]/4/5
=(4/5+0)÷4/5
=4/5÷4/5
=1
