    lets look at teh left hand side \[(10+\frac{5}{8}+3+\frac{5}{8})+2+\frac{3}{8} \\ (10+3+2)+(\frac{5}{8}+\frac{5}{8}+\frac{3}{8})\] can you add 10 and 3 and 2 together?

    \[15+(\frac{5}{8}+\frac{5}{8}+\frac{3}{8})=n+12\]

    oh I guess we can write in fraction form later I was trying to keep it in fraction form because the choices are written as fractions but we can go to decimals if you want then write as fraction

    you don't want to write 1.6 that is an approximation

    \[15+1.625=n+12\]

    \[16.625=n+12 \\ 16.625-12=n\]

    16.625-12? 4.625

    yes 16-12 =4 so 16.625-12=4.625 so if the directions was to "solve for n" you would say 4.625 and there is only one choice above that says 4 and something if the directions say "solve for N" you would say none of these but as you said you meant to say "solve for n" :p
