Enter the answer as an exact decimal or simplified fraction.

Convert to Common Denominator: Convert the fractions to have a common denominator. $\newline$ The fractions $-\frac{13}{20}$ and $\frac{7}{5}$ need to have the same denominator to be subtracted. The least common denominator (LCD) for $20$ and $5$ is $20$ .
Convert to Denominator $20$ : Convert $(\frac{7}{5})$ to a fraction with a denominator of $20$ . $\newline$ To convert $(\frac{7}{5})$ to a fraction with a denominator of $20$ , multiply both the numerator and the denominator by $4$ . $\newline$ $(\frac{7}{5}) \times (\frac{4}{4}) = (\frac{28}{20})$
Rewrite with Common Denominator: Rewrite the subtraction with the common denominator. $\newline$ Now we have $-\frac{13}{20} - \frac{28}{20}$ .
Subtract Numerators: Subtract the numerators and keep the common denominator. $\newline$ Subtract the numerators of the two fractions: $\newline$ $-13 - 28 = -41$ $\newline$ So, $-(13/20) - (28/20) = (-41/20)$ .
Simplify Result: Simplify the result, if possible. $\newline$ The fraction $(-\frac{41}{20})$ is already in simplest form, so no further simplification is needed.
