Add total number of feet together.
=5 3/8+ 7 1/2+ 8 2/5
=5.375 + 7.5 + 8.4
=21.275 total feet of pipe (rounded to the tenths would be 21.3 feet)
Hope this helps! :)

HELLO !
Okay so what you do is<em> eliminate the parenthesis </em>in the equation because it really helps
So you would multiply 8 and b
Also multiple 8 and a
You would get 8b and 8a
Your equation would look like ...
2a + 8b + 8a = ...
<em>Now you add the alike things in the equation </em>
8a and 2a are the alike things.
Now you would have ...
10a + 8b = ?
