Question

 5.{26-[3.(5+2.5)+15]:15}

Answer 1

= 5.{26-[3.15+15]:15}

= 5.{26-[45+15]:15}

= 5.{26-60:15}

= 5.{26-4}

= 5.22

= 110

Answer 2

5. { 26 - [ 3 . ( 5 + 2.5) + 15 ] : 15 }

= 5. { 26 - [ 3 . ( 5 + 10 ) + 15 ] : 15 }

= 5. { 26 - [ 3 . 15 + 15 ] : 15 }

= 5. { 26 - [ 45 + 15 ] : 15 }

= 5. { 26 - 60 : 15 }

=  5. { 26 - 4 }

= 5 x 22 = 110

Answer 3

=\(5\cdot\left\{26-\left[3\cdot15+15\right]:15\right\}\)

=\(5\cdot\left\{26-60:15\right\}\)

=\(5\cdot\left\{26-4\right\}\)

=\(5\cdot22\)

=\(110\)
