Question

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

 

Answer 1

= 3,78 [200-68-(100-68)] = 3,78 (200-68-100+68)

= 378

Answer 2

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

= 3,78 x ( 132 - 32)

= 3,78 x 100

= 378

Answer 3

\(3,78.\left(200-68\right)-3,78.\left(100-68\right)\)

\(=3,78.132-3,78.32\)

\(=3,78.\left(132-32\right)\)

\(=3,78.100=378\)
