8 1/4814 pounds of flour.

Explanation:

If you do 22 (the whole number) times 3 = 63=6.

Leave that for now, make the 3/434 in a percentage:

3/4 * 100% = 75%34100%=75%

Multiply this by 33 and you get 225%225%. Make this percentage into a fraction:

(225%)/(100%) = 2.25= 2 1/4225%100%=2.25=214

Add the two values together:

6+ 2 1/4 = 8 1/46+214=814

Hope this helps!
