Add the following fractions: 3/7 + 1/5

Answer 1

To add fractions, we need to have the same denominator. In this case, the denominators are already different: 7 and 5.

To make the denominators the same, we can find the least common multiple (LCM) of 7 and 5, which is 35.

We can then convert both fractions to have a denominator of 35:

3/7 is equivalent to (3/7) * (5/5) = 15/35
1/5 is equivalent to (1/5) * (7/7) = 7/35

Now that both fractions have a denominator of 35, we can add them:

15/35 + 7/35 = (15 + 7) / 35 = 22/35

So, 3/7 + 1/5 = 22/35
