运用乘法分配律简便计算。
6.5×68+6.5×31+6.5
=6.5×(68+31+1)
=6.5×100
=650
0.27×0.12十0.88×0.27
=.27×(0.12+0.88)
=0.27×1
=0.27。
6.5×68+6.5×31+6.5
=6.5×(68+31+1)
=6.5×100
=650
0.27×0.12十0.88×0.27
=.27×(0.12+0.88)
=0.27×1
=0.27。

=(68+31+1)×6.5
=100×6.5
=650
=(68+31+1)×6.5
=100×6.5

第一题6.5×(68+31)
=6.5×99
=6.5×(100-1)
=650-6.5
=643.5
第二题0.27×(0.12+0.88)
=0.27×1=0.27望采纳
=6.5×99
=6.5×(100-1)
=650-6.5
=643.5
第二题0.27×(0.12+0.88)
=0.27×1=0.27望采纳
