Answer 1

To add fractions with unlike denominators, you need to find a common denominator. In this case, the common denominator is 30.

To convert 1/3 to have a denominator of 30, multiply the numerator and denominator by 10: (1/3) * (10/10) = 10/30.

To convert 7/10 to have a denominator of 30, multiply the numerator and denominator by 3: (7/10) * (3/3) = 21/30.

Now that both fractions have the same denominator, you can add them together: 10/30 + 21/30 = 31/30.

Therefore, the correct response is 31/30.
