(1)5.6X69.32+138.64X0.05+693.2X0.43

(2)362+548X361
——————
362X548-186
简算的哦,第(2)题就是362X548-186分之362+548X361
过程也要哦

(1)5.6X69.32+138.64X0.05+693.2X0.43

=5.6*69.32+69.32*2*0.05+69.32*4.3

=69.32*(5.6+0.1+4.3)

=69.32*10

=693.2

(362+548X361)/(362X548-186 )

=(362+548*361)/[(361+1)*548-186]

=(362+548*361)/[361*548+548-186]

=(362+548*361)/(548*361+362)

=1

(1)388.192+6.932+298.076=693.2
(2)(362*548)*2-186分之362等于就行了

1 5.6*69.32+138.64*0.05+693.2*0.43
= (5.6+138.64+693.2)*(69.32+0.05+0.43)
=837.44*70
=58620.8
2 362*548-362/186+548*361
