bạn tk ủng hộ mk nha!

`a, 1000 : 100 = 10`

`b, 75 xx 100 = 7500`

`c, 900 xx 10 = 9000`

`d, 8 xx 100 : 10 : 10 xx 10000 = 80000`

\(a,1000:100=10\\ b,75\times100=7500\\ c,900\times10=9000\\ d,8\times100:10:10\times10000\\ =800:10:10\times10000=8\times10000=80000\)

a)\(1000:100=10\)
b)\(75\times100=7500\)

c)\(900\times10=9000\)

d)\(8\times100:10:10\times10000=8\times10000=80000\)

123 + 123 + 123

= 246 + 123 

= 369

900 + 900 + 900

= 1800 + 900

= 2700

123+123+123=369

900+900+900=2700

số đó là

123+123+123=123x3=369

900+900+900=900x3=2700

đúng ko vậy bn

3000 + 2 < 3200

6500 + 200 > 6621

8700 – 700 = 8000

9000 + 900 < 10 000

(123 + 123 + 224) x 10 * 100 : 10000 = 47

(123+123+224)x10*100:10000=47

9100 nha bn 

k mình nhé

\(10000-900.1=10000-900=9100\)

chuc bn hoc gioi!
