Least Common Factor(LCM) of 5 and 7: 35

7*5=35
5*7 = 35

Factor of 5 and 7

3/7 + 3/5 = 15/35 + 21/35 = 36/35 = [tex] 1 \frac{1}{35} [/tex]
The first thing you're gonna do is find common denominators:
3/7 + 3/5 now becomes 15/35 + 21/35
Then add the numerators together:
15+21/35
This gives you your answer 36/35, simplify it and you get 1 1/35.
Hope this helps!:)
