Well the first step would be to change each fraction into an improper fraction
8 3/4= 35/4, 2 1/2= 5/2 or 10/4, and 5 1/4= 21/4
Now multiply 35/4 by 10/4 and you get 350/16 but in simplest form it would be 175/8. Multiply that by 21/4 and you get 3,675/32 and change that into a mixed number. The answer would be 114 27/32
The is going to be infinite answers
