Answer 2

A) (3/4) + (2/3) + (1/5) = 3/4 + 2/3 + 1/5.............(mmc = 60)

..............................................= (45 + 40 + 12) / 60

..............................................= 97 / 60

B)..(6/3) + (5/4) + (1/8) = 6/3 + 5/4 + 1/8

..............................................= 2/1 + 5/4 + 1//8............(mmc = 8)

..............................................= (16 + 10 + 1) / 8

..............................................= 27 / 8

C)..(3/6) + (4/8) + (5/4) = 3/6 + 4/8 + 5/4

..............................................= 1/2 + 1/2 + 5/4................(mmc = 4)

..............................................= (2 + 2 + 5) / 4

..............................................= 9 / 4
