\frac{100P}{100}+\frac{PR\times 1}{100}
To add or subtract expressions, expand them to make their denominators the same. Multiply P times \frac{100}{100}.
\frac{100P+PR\times 1}{100}
Since \frac{100P}{100} and \frac{PR\times 1}{100} have the same denominator, add them by adding their numerators.
\frac{100P+PR}{100}
Do the multiplications in 100P+PR\times 1.
\frac{100P+PR}{100}
Factor out \frac{1}{100}.
P\left(100+R\right)
Consider 100P+PR. Factor out P.
\frac{P\left(R+100\right)}{100}
Rewrite the complete factored expression.
