Multiply the numerators of the two fractions:
\[
-6 \times 11 = -66
\]
Step 2: Multiply the denominators
Multiply the denominators of the two fractions:
\[
5 \times 10 = 50
\]
Step 3: Simplify the fraction
Combine the results from Step 1 and Step 2 to form the fraction:
\[
-\frac{66}{50}
\]
Simplify the fraction by dividing the numerator and denominator by their greatest common divisor (GCD), which is 2:
\[
-\frac{66 \div 2}{50 \div 2} = -\frac{33}{25}
\]
