Question

2,4*10,5+1,8*10,5

Answer 1

\(=10,5\times\left(2,4+1,8\right)\)

\(=10,5\times4,2\)

\(=44,1\)

Answer 2

\(2,4\times10,5+1,8\times10,5\)

\(=10,5\times\left(2,4+1,8\right)\)

\(=10,5\times4,2\)

\(=44,1\)

Answer 3

\(\frac{r}{ẻ\hept{\begin{cases}\\1113\\\end{cases}}\frac{v}{t3rt\hept{\begin{cases}\\210\\\end{cases}}}f}\)

Answer 4

2,4 * 10,5 + 1,8 * 10,5

= 10,5 * (2,4 + 1,8)

= 10,5 * 4,5

= 44,1
