w=\frac{4}{5}+\frac{1}{4}
Add \frac{1}{4} to both sides.
w=\frac{16}{20}+\frac{5}{20}
Least common multiple of 5 and 4 is 20. Convert \frac{4}{5} and \frac{1}{4} to fractions with denominator 20.
w=\frac{16+5}{20}
Since \frac{16}{20} and \frac{5}{20} have the same denominator, add them by adding their numerators.
w=\frac{21}{20}
Add 16 and 5 to get 21.
