[tex]\frac{7}{64}+20\frac{7}{8}+\frac{5}{32}=\ \ \ \ | make\ common\ denominators\\\\ \frac{7}{64}+20\frac{56}{64}+\frac{10}{64}=20\frac{7+56+10}{64}=20\frac{73}{64}=21\frac{9}{64}\\\\ Solution\ is\ 21\frac{9}{64}.[/tex]
firs make the botom numbers the smae
the smallest number all of them will go into is 64
7/64
20 and 7/8

167/8
multiply by 8/8
1336/64

5/32
multiply by 2
10/64
add 7/64+1336/64+10/64=1353/64=21 and 9/64
