120 x 100 + 120 x 100 - 120 x 100
= (120 x 100) + (120 x 100) - (120 x 100)
= 12000 + 12000 - 12000
= 24000 - 12000
= 12000

Lời giải:
$100=2^2.5^2$
$120=2^3.3.5$
$\Rightarrow ƯCLN(100,120)=2^2.5=20$

120 : 30 x 100 + 1000 - 100 =?
= 4 x 100 + 1000 - 100
= 400 + 1000 - 100
= 1400 - 100
= 1300
120 : 30 x 100 + 1000 - 100
= 4 x 100 + 1000 - 100
= 400 + 1000 - 100
= 1400 - 100
= 1300
