Answer 1

(32 + 36 ) / 4 = 32/4 + 36/4 = 68/4

( 49 + 56 ) / 7 = 49/7 + 56/7 = 105 / 7

( 18 + 42) / 6 = 18/6 + 42 / 6 = 60 / 6 = 10 

( 270 + 150) / 3 = 270 / 3 + 150 / 3 = 420 / 3 = 140

( 810 - 450 ) / 90 = 810 / 90 - 450 / 90 = 360 / 90 = 4

( 500 - 350 ) / 50 = 500 / 50 - 350 / 50 = 150 / 50 = 3 


B) 

( 8 + 10 + 6) / 2 = 8/2 + 10/2 + 6/2   ( Adevarat) 

100 / ( 20 + 5 ) =  100 / 20 + 100 / 05   ( Fals)
