ket qua bang 12400

số đó là

12300+100=12400

ai k mìn

mình k laijc ho

123 x 100 + 100

= 12300 + 100

= 12400

123 x 100 = 12300

1 x 100 = 100

k mik nha TRANHOANGHAI

bài giải

123 x 100 = 12300

1 x 100 = 100

hi

12300

100

x - 100 = 123 - 123

x - 100 = 0

x         = 0 + 100

x         = 100

x-100=123-123

x-100=0

x=100+0

x=100

x-100=123-123

x-100=0

x=0+100

x=100

k nha

12300,1200,1111

nha bạn

123 x 100 = 12300

12 x 100 = 1200

1100 + 11 = 1111

hi

123 x 100

= 1230

12 x 100

= 1200

1100 + 11

= 1111

\(a,123\times54+27\times123-12\times123+123\times31\)

\(=123\times\left(54+27-12+31\right)\)

\(=123\times100\)

\(=12300\)

\(b,\dfrac{121}{27}\times\dfrac{54}{11}< n< \dfrac{100}{21}:\dfrac{25}{126}\)

\(22< n< \dfrac{100}{21}\times\dfrac{126}{25}\)

\(22< n< 24\)

Vì \(23>22\) và \(23< 24\) nên \(n=23\)

a, 123x(54+27-12+31)

=123x100

=12300

a123x54+27x123-12x123+123x31

=123:54+27:123-12:123+123:31

=6642+27:123-12:123+123:31

=6642+3321-12:123+123:31

=6642+3321-1476+123:31

=6642+3321-1476+3813

=12300

b,121/27x54/11<n>100/21:25/126

=22<n>24

n=23

Bằng 123000

dễ mà bạn

12300

123 x 100 = 12300 nha bn

123 x 100 = 12300
