Answer:
2/5
Step-by-step explanation:
To simplify 6/15, we need the lowest common multiple of 6 and 15. This is so we can divide the numerator and the denominator by this number. The LCM of 6 and 15 can be determined by prime factorization:
6=2*3
15=5*3
As you can see, 3 appears in both numbers as a factor of each, so 3 is the LCM.
If we divide the numerator 6 by 3, we get 2
If we divide the denominator 15 by 3, we get 5
So the simplified fraction is 2/5
