Q. Perform the operation and reduce the answer fully. Make sure to express your answer as a simplified fraction.−94⋅25Answer:
Multiply Numerators: Multiply the numerators of the two fractions.To multiply two fractions, you multiply the numerators (top numbers) together and the denominators (bottom numbers) together. In this case, we multiply the numerators −4 and 5.−4×5=−20
Multiply Denominators: Multiply the denominators of the two fractions.Now we multiply the denominators 9 and 2.9×2=18
Write Result as Fraction: Write the result as a fraction.The result from Step 1 becomes the numerator, and the result from Step 2 becomes the denominator.The fraction is −1820.
Simplify Fraction: Simplify the fraction.To simplify the fraction, we need to find the greatest common divisor (GCD) of the numerator and the denominator and divide both by that number. The GCD of 20 and 18 is 2.−20÷2=−1018÷2=9
Write Simplified Fraction: Write the simplified fraction.After dividing both the numerator and the denominator by the GCD, we get the simplified fraction −910.
