5v - \(\frac{4}{10}\) = \(\frac{4}{5}\)   Multiply both sides by 10
50v - 4 = \(\frac{40}{5}\)   Divide the fraction
50v - 4 = 8   Add 4 to both sides
50v = 12   Divide both sides by 50
v = \(\frac{12}{50}\)   SImplify the fraction
v = \(\frac{6}{25}\)

5v= 4/5 + 4/10
5v= 8/10 + 4/10
5v= 12/10
5v= 6/5
V= 6/25
