You have two fractions with denominators of 3 and 10. What number should you use as the least common denominator if you want to add them?

Answer 1

9514 1404 393

Answer:

30

Explanation:

The least common denominator is the least common multiple of the denominators.

Here, the given denominators, 3 and 10, have no common factors, so their least common multiple is simply their product:

LCD = 3×10 = 30

The least common denominator is 30.

If the denominator numbers have a common factor, then their least common multiple is their product divided by their greatest common factor.
