\(\left(158x129-158x39\right):18\)

\(=\left[158\left(129-39\right)\right]:18\)

\(=158.90:18\)

\(=14220:18\)

\(=790\)

Answer 3

      \(\left(158.129-158.39\right):18\)

\(=\left[158.\left(129-39\right)\right]:18\)

\(=\left[158.90\right]:18\)

\(=14220:28\)

\(=790\)

Answer 4

( 158 . 129 - 158 . 39 ) : 18 

= [ 158 . ( 129 -39)] : 18 

= [ 158 .90 ] : 18

= 14220 : 18

= 790 

Answer 5

(158.129—158x39):18

=158.(129—39):18

=790

Answer 6

(158 x 129 - 158 x 39) : 180

= 158 x (129 - 39) : 18

= 158 x 90 : 18

= 4220 : 18

= 790

Answer 7

( 158 x 129 - 158 x 39 ) : 180

= ( 158 x ( 129 - 39 ) ) : 180

= ( 158 x 90 ) : 180

= 14220 : 180

= 790

Answer 8
