Answer 1

a, 96 x 123,47 + 123,47 :0,25

=96 x 123,47 + 123, x 4

=123,47 x ( 96 + 4 )

=123,47 x 100

= 12347

b, 1008 x 2,015 + 2,015 : 0,125

=1008 x 2,015 + 2,015 x 8

=2,015 x ( 1008 + 8 )

=2,015 x 1016

=2047,24 

Answer 2

=96 x 123,47 + 123, x 4
=123,47 x ( 96 + 4 )
=123,47 x 100
= 12347
b, 1008 x 2,015 + 2,015 : 0,125
=1008 x 2,015 + 2,015 x 8
=2,015 x ( 1008 + 8 )
=2,015 x 1016
=2047,24

Answer 3

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

= 12347

b 1008 x 2.015 + 2.015 : 0.125

=1008 x 2.015 + 2.015 x 8

=(1008 + 8)x 2.015

=2016 x 2.015

=4062.24

Answer 4

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

Answer 5

a=12347

b=2047,24

Answer 6

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

Answer 7

2047,24
