0,24*450+0,8*15*3+3*4*8

Answer 1

[456]

\(0,24\times450+0,8\times15\times3+3\times4\times8\)

\(=0,24\times100\times4,5+0,8\times3\times15+3\times8\times4\)

\(=24\times4,5+2,4\times10\times1,5+24\times4\)

\(=24\times4,5+24\times1,5+24\times4\)

\(=24\times\left(4,5+1,5+4\right)\)

\(=24\times10\)

\(=240\)
