M+2 1/4=8 4/5 pls show your work . a) 6 3/1 b) 11 1/20 c) 6 11/20 d) 6 9/20

Please include the instructions.  It appears that you want to find the value of m that makes m + 2 1/4 = 8 4/5, but you should state this explicitly.

Rewrite   m + 2 1/4 = 8 4/5   as   m + 2.25 = 8.80.
Subtr. 2.25 from both sides:        m             = 6.55   (answer)

This is also equal to 131/20 or 6 11/20.

Next time, would you please insert punctuation in your list of answers, to separate A from B, B from C, and so on.
