Add or subtract as indicated. Write answers in lowest terms as needed. 7/12 + 1/12

Key Concepts

Common Denominators

To add or subtract fractions, they must have a common denominator. The denominator is the bottom part of a fraction, and it indicates how many equal parts the whole is divided into. In this case, both fractions, 7/12 and 1/12, already share the same denominator of 12, allowing for straightforward addition.

Adding Fractions

When adding fractions with a common denominator, you simply add the numerators (the top parts of the fractions) while keeping the denominator the same. For example, in the expression 7/12 + 1/12, you would add 7 and 1 to get 8, resulting in 8/12 as the sum.

Lowest Terms

Expressing a fraction in lowest terms means simplifying it to its simplest form, where the numerator and denominator have no common factors other than 1. In the case of 8/12, both 8 and 12 can be divided by 4, simplifying the fraction to 2/3, which is its lowest terms.
