45

Explanation:

Start by converting your mixed numbers into improper fractions. To do this, lets look at 8 3/4.

To convert a mixed number into an improper fraction, you multiply the denominator (4) by the number out in front (8) , then add the numerator (3), then put that number over the original denominator (4) So to write that out, you take 4*8+3 , which equals 35, so 8 3/4 = 35/4.
Repeat this with 5 1/7 to get 36/7.
Now, we are able to easily multiply across:
35/4 * 36/7 = 1260/28 = 45
