Question

(u/x)+(5u/x)+(u/5x)

Answer 1

\[\frac{ u }{x }+\frac{ 5u }{ x }+\frac{ u }{ 5x } \]

Answer 2

\[\huge \frac{u}{x} + \frac{5u}{x} +\frac{u}{5x} \]
In order to solve such problems we must have denominators equal, hence:
\[\huge \frac{u}{x} + \frac{5u}{x} +\frac{u}{5x} =\huge \frac{5u}{5x} + \frac{5 \times 5u}{5x} +\frac{u}{5x} \]
\[\huge = \frac{5u}{5x} + \frac{25u}{5x} +\frac{u}{5x} \]
\[\huge = \frac{5u + 25u +u}{5x} =\frac{31u}{5x}\]
is the required answer.
