325x6+6x560+115x6

133:7+154:7+413:7

Answer 1

\(325.6+6.650+115.6\)

\(=6.\left(325+650+115\right)\)

\(=6.1090\)

\(=6540\)

\(133:7+154:7+413:7\)

\(=\left(133+154+413\right):7\)

\(=700:7\)

\(=100\)

Answer 2

\(325.6+6.560+115.6\)

\(=6.\left(325+560+115\right)\)

\(=6.1000\)

\(=6000\)

\(133:7+154:7+413:7\)

\(=\left(133+154+413\right):7\)

\(=700:7\)

\(=100\)

Answer 3

325 x 6 + 6 x 560 + 115 x 6

= ( 325 + 560 + 115 ) x 6

= 1000 x 6

= 6000

133 : 7 + 154 : 7 + 413 : 7

= ( 133 + 154 + 413 ) : 7

 = 700 : 7
