a 96 x 123.47 + 123.47 : 0,25
=96 x 123.47 + 123.47 x 4
=(96 + 4) x 123.47
=100 x 123.47

a) 96*123.47+123.47/0.25=96*123.47+123.47*4=123.47*(96+4)=123.47*100=12347
b)1008*2.015+2.015/0.125=1008*2.015+2.015*8=2.015*(1008+8)=2.015*1016=2047.24
a.96 x 123,47 + 123,47 : 0.25
= 123,47 x 96 + 123,47 x 4
= 123,47 ( 96 + 4 )
= 123,47 x 100
= 12347
b, 1008 x 2,015 + 2, 015 : 0,125
= 2,015 x 1008 + 2,015 x 8
= 2,015 x ( 1008 + 8)
= 2,015 x 1016
= 2,015 x 1000 + 16 x 2,015
= 2015 + 32,24
= 2047,24
Vậy :96 x 123,47 + 123,47 : 0.25 = 12347
1008 x 2,015 + 2, 015 : 0,125 = 2047,24
