简便计算:2.74×9.5+5×0.274
2.74×9.5+5×0.274
=2.74×9.5+0.5×2.74
=2.74×(9.5+0.5)
=2.74×10
=27.4

2.74×9.5+5×0.274
=0.274*95+5×0.274
=0.274*(95+5)
=27.4

=2.74×9.5+0.5×2.74
=2.74×(9.5+0.5)
=27.4

2.74×9.5+5×0.274=0.274*95+5×0.274=(95+5)*0.274=27.4

2.74×9.5+0.5×2.74
=(9.5+0.5)×2.74
=10×2.74
=27.4

原式=2.74*9.5+0.5*2.74
=2.74*(9.5+0.5)
=2.74*10
=27.4

原式=2.74×9.5+0.5×2.74=2.74×10=27.4

2.74*9.5+5*0.274
=2.74*(9.5+0.5)
=27.4

2.74×9.5+5×0.274
=2.74×9.5+0.5×2.74
=2.74×(9.5+0.5)
=2.74×10
=27.4

2.74×9.5+5×0.274
=2.74×9.5+0.5×2.74
=2.74×(9.5+0.5)
=2.74×10
=27.4
