19.85+15.19+130 = 19.(85+15)+130
= 19.100+130
= 1900+130
= 2030
\(19.85+15.19+130\)
\(=19\left(85+15\right)+130\)
\(\Rightarrow19.100+3.100\)
\(=100\left(19+3\right)=100.22\)
\(=2200\)
19.85 + 15.19 + 130
= 19. ( 85 + 15) + 130
= 19. 100 +130
= 1900 + 130
= 2030
nhé
19.85+ 15 .19+ 130
= 19 . (85 + 15) + 130
= 19 . 100 + 130
= 1900+130
= 2030
19.85+15.19+130
=19.(85+15)+130
=19.100+130
=1900+130
=2030
19.85+15.19+130
=19.(85+15)+130
