Giải:
\(15.91,5+150.0,85\)
\(=150.9,15+150.0,85\)
\(=150.\left(9,15+0,85\right)\)
\(=150.10\)
\(=1500\)
Vậy ...
15.91,5+150.0,85
=150.9,15+150.0,85
=150.(9,15+0,85)
=150.10
=1500
Vậy....
15 x 91,5 + 150 x 0,85
*Giải :
=150,0 x 9,15 + 150,0 x 0,85
= 150,0 x (9,15 + 0,85)
= 150,0 x 10,0
=1500,0
Vậy 15 x 91,5 + 150 x 0,85 = 1500,0 .
