(2,4+1,8)x10,5  2,4x10,5+1,8x10,5

(2,9+3,6)x0,25  2,9x0,25+3,6x0,25

Answer 1

[Nguyễn Lê Phước Thịnh]

a: \(\left(2,4+1,8\right)\cdot10,5=4,2\cdot10,5=44,1\)

\(2,4\cdot10,5+1,8\cdot10,5=25.2+18,9=44,1\)

b: \(\left(2,9+3,6\right)\cdot0,25=6,5\cdot0,25=1,625\)

\(2,9\cdot0,25+3,6\cdot0,25=0,725+0,9=1,625\)
