[tex]b \: \% = \frac{b}{100} \\ [/tex]
[tex] \frac{b}{100} \times 30 = 27 \\ \frac{3b}{10} = 27 \\ 3b = 270 \\ b = \frac{270}{3} \\ b = 90[/tex]
a% = (a/100) de (multiplicación) es (=) b (90)
[tex] \frac{a}{100} \times 300 = 90 \\ 3a = 90 \\ a = \frac{90}{3} \\ a = 30[/tex]
[Respuesta] El valor de a es 30% ✔
