Question

calcule as adiçoes e se possivel simplifique as somas encontradas 5/8+1/3 e 1/3+2/5+1/15

Answer 1

5 + 1   =  3.5 + 8.1 = 15 + 8  =   23
8    3          24              24         24

mmc = 8,3 = 24
**************************************************
8,3: 2
4, 3: 2
2, 3: 2
1,3: 3
1,1      =2.2.2.3 = 8.3 = 24
------------------------------------------------------------------------------

1 + 2 + 1    =  5.1 + 3.2 + 1.1 =  5 + 6 + 1  =  12  (:3) =  4
3    5   15             15                        15          15 (:3)     5

mmc (3,5) = 15

3,5,15: 3
1,5,5: 5
1,1,1     = 3.5 = 15
