OBSERVAÇÃO : PRECISO DA CONTA E DO MMC

Answer 1

5/3 + 4/5 + 7/15
mmc= 15

25/15 + 12/15 + 7/15

37/15 + 7/15

      44/15

Answer 2

5/3 + 4/5 + 7/15

3,5,15 | 3
1,5,5 | 5
1,1,1

mmc(3,5,15) = 3.5 = 15

(15/3).5 = 5.5 = 25
(15/5).4 = 3.4 = 12
(15/15).7 = 1.7 = 7

25/15 + 12/15 + 7/15 = 

37/15 + 7/15 = 

44/15
