23,25 .175 -23,25 .76 + 23,25

 

Answer 1

\(23,25.175-23,25.76+23,25\)

\(=23,25.\left(175-76+1\right)\)

\(=23,25.100=2325\)

Answer 2

\(...=23,5\left(175-76+1\right)=23,5.100=2350\)

Answer 3

23,25 . 175 - 23,25 . 76 + 23,25

= 23,25 . 175 - 23,25 . 76 + 23,25 . 1

= 23,25 . ( 175 - 76 + 1 )

= 23,25 . ( 99 + 1 )

= 23,25 . 100

= 2 325
