Question

3,78*(200-68)-3,78*(100-68)

Answer 1

= 3,78 x 132 - 3,78 x 32

= 3,78 x 100

= 378

Answer 2

3,78 x ( 200 - 68 ) - 3,78 x ( 100 - 68 )

= 3,78 x 132 - 3,78 x 32

= 3,78 x ( 132 - 32 )

= 3,78 x 100

= 378

Answer 3

\(3.78\cdot\left(200-68\right)-3.78\cdot\left(100-68\right)\)

\(=3.78\cdot\left[\left(200-68\right)-\left(100-68\right)\right]\)

\(=3.78\cdot\left(200-68-100+68\right)\)

\(=3.78\cdot\left[\left(200-100\right)+\left(-68+68\right)\right]\)

\(=3.78\cdot100\)

\(=378\)

Answer 4

3,78 x ( 200 - 68 ) - 3,78 x ( 100 - 68 )

= 3,78 x 132 - 3,78 x 32

= 3,78 x ( 132 - 32 )

= 3,78 x 100

= 378

Answer 5

3,78 x ( 200 - 68 ) - 3,78 x ( 100 - 68 )

= 3,78 x 132 - 3,78 x 32

= 3,78 x ( 132 - 32 )

= 3,78 x 100

= 378
