Answer 1

5.5*17.3 6.7*5.5是不是用脱式来计算做的

脱式计算
5.5*17.3+ 6.7*5.5
=5.5x(17.3+6.7)
=5.5x24
=5.5x4x6
=22x6
=132

5.5×17.3 2.7×5.5(脱试计算)

5.5×17.3+ 2.7×5.5
=5.5x(17.3+2.7)
=5.5x20
=110

5.5×9.9+0.1×5.5脱式计算

5.5×9.9+0.1×5.5
=5.5×(9.9+0.1)
=5.5×10
=55

5.5*4.04的脱式计算

5.5*4.04
=5.5*4+5.5*0.04
=22+0.22
=22.22

=24.75÷0.9
=27.5

5.5乘9.8脱式计算

5.5×9.8
=5.5×(10-0.2)
=5.5×10-5.5×0.2
=55-1.1
=53.9

5.5-4.82+7.08脱式计算

5.5-4.82+7.08
=5.5-5+0.18+7+0.08
=7.5+0.26
=7.76

5.5×40+4.5脱式计算

5.5×40+4.5和是（224.5）
5.5×40+4.5
=220+4.5
=224.5

5.5×17.3+67×55的简便计算

=55×17.3+6.7×55
=（17.3+6.7）×55
=24×55
=1320

5.5乘以8.2+1.8乘以5.5脱式计算

5.5×8.2+1.8×5.5
=5.5×（8.2+1.8）
=5.5×10
=55
