i believe this is multiplication so. just multiply 12 3/4 x 2/5. The answer to that would be 12 6/20. Now let's simplify. you can divide this fraction to the fraction 2/2. 12 6/20 divided by 2/2 equals to 12 3/4. I hope this right, and I really hope you get an A on your test.

If it's division than here's the steps. KCFM (keep, change, flip, multiply) keep 12 3/4, change the division symbol to multiplication, and flip the fraction 2/5 to 5/2. last step multiply. 12 15/8. If you can simplify that then simplify it. I don't see anyone to simplify it so your okay.
