what is 1/3 plus 7/10, give me the answer AND simplification of the answer

To add 1/3 and 7/10, you need to find a common denominator. The least common multiple (LCM) of 3 and 10 is 30. Therefore, you can rewrite the fractions with the common denominator of 30:

1/3 = 10/30
7/10 = 21/30

Now, add the fractions:

10/30 + 21/30 = 31/30

The answer is 31/30, which cannot be simplified further because 31 and 30 do not have any common factors other than 1.
