Question

12 000 - (1500 .2 + 1800 . 3 + 1800 .2 : 3)

Answer 1

12 000 - ( 1500 . 2 + 1800 . 3 + 1800 . 2 : 3)

= 12 000 - ( 3000 + 5400 + 3600 : 3)

= 12 000 - ( 3000 + 5400 + 1200 )

= 12 000 - ( 8400 + 1200 )

= 12 000 - 9600

= 2400

Answer 2

12 000 - ( 1500 . 2 + 1800 . 3 + 1800 . 2 : 3 )

= 12 000 - ( 3000 + 5400 + 1200 )

= 12 000 - 9600

= 2400

Answer 3

12000 - (1500 . 2 + 1800 . 3 + 1800 . 2 : 3)

= 12000 - (300 + 5400 + 3600 : 3)

= 12000 - (5700 + 1200)

= 12000 - 4500

= 7500.
