Simplify 5/14a + -2/5c + 1/8b -2/5c + 3/8b + 7/14a

To simplify the expression 5/14a + -2/5c + 1/8b -2/5c + 3/8b + 7/14a, we can combine like terms.

First, let's combine the terms with "a":

5/14a + 7/14a = (5 + 7)/14a = 12/14a = 6/7a

Next, let's combine the terms with "b":

1/8b + 3/8b = (1 + 3)/8b = 4/8b = 1/2b

Finally, let's combine the terms with "c":

-2/5c + -2/5c = (-2 - 2)/5c = -4/5c

So the simplified expression is 6/7a + 1/2b - 4/5c.
