\(6,1\times98+6,1\times2=6,1\times\left(98+2\right)=6,1\times100=610\)

\(19,7\times4\times2,5=19,7\times10=197\)

A) 6,10 X 98 + 6,10 X 2 

= 597,8 + 12,2

=  610

B) 19,7 x 4 x 2,5

= 78,8 x 2,5 

= 197

a) 6,10 × 98 + 6,10 × 2

= 6,10 × (98+2)

= 6,10 × 100

= 610

b) 19,7 × 4 × 2,5

= 19,7 × (4×2,5)

= 19,7 × 10

= 197

a. 6,10 x 98 + 6,10 x 2 = 6,10 x ( 98 + 2 ) = 6,10 x 100 = 610

b. 19,7 x 4 x 2,5 = 19,7 x ( 4 x 2,5 ) = 19,7 x 10 = 197
