Step 2: Convert Fractions to Have the Common Denominator

To convert -3/7 and -1/4 to have a common denominator of 28, we can multiply the numerator and denominator of each fraction by the same value: - For -3/7, we multiply both the numerator and denominator by 4 to get -12/28. - For -1/4, we multiply both the numerator and denominator by 7 to get -7/28.

Step 3: Perform the Subtraction

Now that both fractions have a common denominator, we can simply subtract the numerators while keeping the common denominator: - (-12/28) + (-7/28) = -19/28
