c. Convert the following mixed number into an improper fraction. Simplify your answer and express it in lowest terms, if applicable. \( -7 \frac{1}{2}= \) Enter any negative signs in the numerator

To convert the mixed number \(-7 \frac{1}{2}\) into an improper fraction, first multiply the whole number part by the denominator: \(7 \times 2 = 14\). Then, add the numerator: \(14 + 1 = 15\). Since it's negative, we keep the negative sign in the numerator: \(-15\). The denominator remains \(2\), so we have \(-\frac{15}{2}\). Now, let's simplify! Fortunately, \(-\frac{15}{2}\) is already in its lowest terms, as 15 and 2 have no common factors. So, the answer is \(-\frac{15}{2}\).
