Answer 3

Performing Arithmetic Operations with Fractions

To perform the arithmetic operations with the given fractions, we'll need to follow the specific steps for each operation.

Addition: To add fractions, we need to ensure that the denominators are the same. Once the denominators are the same, we can simply add the numerators together and keep the denominator the same.

For the given fractions -1/3, 1/4, and 5/12: - To add -1/3 and 1/4, we need to find a common denominator. The least common multiple of 3 and 4 is 12. So, we'll convert -1/3 to an equivalent fraction with a denominator of 12 by multiplying both the numerator and denominator by 4, resulting in -4/12. Then, we can add 1/4 and -4/12. - After finding the common denominator, we add the numerators: 1 + (-4) = -3. So, the result is -3/12.

Subtraction: Subtracting fractions follows a similar process to addition. We ensure that the denominators are the same and then subtract the numerators while keeping the denominator the same.

For the given fractions -1/3, 1/4, and 5/12: - To subtract 5/12 from the result of the addition, we need to ensure that the denominators are the same. Since the result of the addition is -3/12, we can directly subtract 5/12 from it. - Subtracting the numerators: -3 - 5 = -8. So, the result is -8/12.

Therefore, the result of the given arithmetic operation with the fractions -1/3, 1/4, and 5/12 is -8/12.
