Answer 1

333 × 27 + 111 × 19

= 111 × 3 × 27 + 111 × 19

= 111 × 81 + 111 × 19

= 111 × (81 + 19)

= 111 × 100

= 11100

Answer 2

333x27+111x19

=8991+2109

=11100

Answer 3

\(333\cdot27+111\cdot19\)

\(=111\cdot\left(3\cdot27+19\right)\)

\(=111\cdot\left(81+19\right)\)

\(=111\cdot100\)

\(=11100\)
