Studdy Solution

STEP 1

Assumptions1. We are multiplying two fractions. . The fractions are 89\frac{-8}{9} and 722\frac{-7}{22}.

STEP 2

To multiply two fractions, we multiply the numerators (the top numbers) together and the denominators (the bottom numbers) together.
(89)(722)=8×79×22\left(\frac{-8}{9}\right)\left(\frac{-7}{22}\right) = \frac{-8 \times -7}{9 \times22}

STEP 3

Now, we can calculate the product of the numerators and the product of the denominators.
8×79×22=56198\frac{-8 \times -7}{9 \times22} = \frac{56}{198}

STEP 4

The fraction 56198\frac{56}{198} can be simplified by dividing both the numerator and the denominator by their greatest common divisor (GCD). The GCD of56 and198 is2.
56198=56÷2198÷2=2899\frac{56}{198} = \frac{56 \div2}{198 \div2} = \frac{28}{99}So, the product of (89)(722)\left(\frac{-8}{9}\right)\left(\frac{-7}{22}\right) is 2899\frac{28}{99}.
