数学简便计算:8.8-7/9-(0.8+7/9) 1/5x27+3/5x41
数学简便计算:8.8-7/9-(0.8+7/9) 1/5x27+3/5x41
数学简便计算:8.8-7/9-(0.8+7/9) 1/5x27+3/5x41
8.8-7/9-(0.8+7/9)=8.8-0.8-7/9*2=8-14/9=58/9
1/5x27+3/5x41=1/5*27+(3/5÷3)*(41*3)=1/5*27+1/5*123=1/5*150=30
(1)8.8-7/9-(0.8+7/9)
=8.8-0.8-7/9*2
=8-14/9
=58/9
(1)1/5x27+3/5x41
=1/5*27+(3/5÷3)*(41*3)
=1/5*27+1/5*123
=1/5*150
=30

=8.8-7/9-(108/5+21/5)+3/5*41
=44/5-7/9-108/5-21/5+3/5*41 然后通分
