Step 1: Multiply the numerators (top numbers):

$5\times 9=45$

Step 2: Multiply the denominators (bottom numbers):

$9\times 8=72$

So the product of the two fractions is:

$\frac{45}{\mathrm{72<span></span>}}$

Step 3: Simplify the fraction.

We need to find the greatest common divisor (GCD) of 45 and 72. The GCD of 45 and 72 is 9.

Now divide both the numerator and the denominator by 9:

$\frac{45÷9}{72÷9}=\frac{5}{\mathrm{8<span></span>}}$

Final Answer:

The simplified answer is $\frac{5}{8}\backslash frac\{5\}\{8\}$​.

Explanation:

To multiply fractions, you multiply the numerators together and the denominators together. Then, simplify the resulting fraction by dividing the numerator and denominator by their greatest common divisor.
