\frac{F}{T}+V\times \frac{Y}{V}
Express F\times \frac{1}{T} as a single fraction.
\frac{F}{T}+Y
Cancel out V and V.
\frac{F}{T}+\frac{YT}{T}
To add or subtract expressions, expand them to make their denominators the same. Multiply Y times \frac{T}{T}.
\frac{F+YT}{T}
Since \frac{F}{T} and \frac{YT}{T} have the same denominator, add them by adding their numerators.
