Answer 1

a, (44 × 8 + 16 × 3) : (17 × 2 - 6 × 5 - 3)

=[16 x 2 + 16 x 3 ] : ( 17 x 2 - 6 x 5 - 3 )

= 80 : 1

=80

b, (500 × 9 - 250 × 18 ) × (500 × 99 + 500)

= 0 x (500 × 99 + 500)

=0

Answer 2

a) (44 x 8 + 16 x 3) : (17 x 2 - 6 x 5 - 3)

= ( 352 + 48) : (34 - 30 - 3)

= 400 : ( 4 - 3)

= 400 : 1 = 400

a, (500 x 9 - 250 x 18) x (500 x 99 + 500)

= (4500 - 4500) x (49500 + 500)

= 0 x 50000

= 0
