Cảm ơn trước

 

Answer 1

Ta có:

\(18,5:4,6+14,8:4,6+12,7:2:2,3\)

\(=18,5:4,6+14,8:4,6+12,7:\left(2\text{x}2,3\right)\)

\(=18,5:4,6+14,8:4,6+12,7:4,6\)

\(=\left(18,5+14,8+12,7\right):4,6\)

\(=46:4,6\)

\(=10\)

thanks nha

Answer 3

$18,5:4,6+14,8:4,6+12,7:2:2,3$

$=18,5:4,6+14,8:4,6+12,7:\left(2\text{x}2,3\right)$

$=18,5:4,6+14,8:4,6+12,7:4,6$

$=\left(18,5+14,8+12,7\right):4,6$

$=46:4,6$

$=10$

$18,5:4,6+14,8:4,6+12,7:2:2,3$

$=18,5:4,6+14,8:4,6+12,7:\left(2\text{x}2,3\right)$

$=18,5:4,6+14,8:4,6+12,7:4,6$

$=\left(18,5+14,8+12,7\right):4,6$

$=46:4,6$

$=10$
