10/16 + 3/24 = (5*2) / (8*2) + (1*3)/( 8*3) == 5/8 + 1/8 = 6/8 = (3*2) /(4*2) = 3/4
30/45 + 8/36 = (6*5) /(9*5) + (2*4)/ (9*4) = 6/9+ 2/9= 8/9
60/120 + 75/150 = (1*60) / (2*60) + (1*75)/ (2*75)=
= 1/2 + 1/2 = 2/2 =1
24/360 + 16/480 = (2*12)/ (30*12) + (1*16)/ (30*16) =
= 2/30 + 1/30 = 3/30 = (1*3)/(10*3) = 1/10
