Lời giải:
$20,18\times 8,5+20,18+20,18:2$
$=20,18\times 8,5+20,18\times 1+20,18\times 0,5$
$=20,18\times (8,5+1+0,5)=20,18\times 10=201,8$

\(47.20,18+360.2,018+1,7.201,8\)
\(=47.20,18+36.\left(10.2,018\right)+\left(1,7.10\right).20,18\)
\(=47.20,18+36.20,18+17.20,18\)
\(=20,18.\left(47+36+17\right)\)
\(=20,18.100=2018\)
47 x 20,18 + 360 x 2,018 + 1,7 x 201,8
= 47 x 20,18 + 36 x 10 x 2,018 + 1,7 x 10 x 20,18
= 47 x 20,18 + 36 x 20,18 + 17 x 20,18
= 20,18 x ( 47 + 36 + 17 )
= 20,18 x 100
= 2018

a) 25,5 : 0,2 + 25,5 : 0,125 - 25,5 x 2 - 25,5
= 25,5 x 5 + 25,5 x 8 - 25,5 x 2 - 25,5 x 1
= 25,5 x (5 + 8 - 2 - 1)
= 25,5 x 10
= 255
b) 20,18 x 7,5 + 20,18 x 2 + 20,18 : 2
= 20,18 x 7,5 + 20,18 x 2 + 20,18 x 0,5
= 20,18 x (7,5 + 2 + 0,5)
= 20,18 x 10

a) \(25,5:0,2+25,5:0,125-25,5\times2-25,5\)
\(=25,5\times5+25,5\times8-25,5\times2-25,5\)
\(=25,5\times\left(5+8-2-1\right)\)
\(=25,5\times10=255\)
