Resolviendo la ecuación, primero simplificamos la fracción del lado derecho: \( \frac{0.2}{0.8} = \frac{1}{4} \). Ahora, igualamos las fracciones: \( \frac{1.3}{T} = \frac{1}{4} \). Multiplicamos en cruz: \( 1.3 \cdot 4 = 1 \cdot T \), lo que nos da \( T = 5.2 \). ¡Así que el número que debe reemplazar a T es 5.2! Para verificar, puedes sustituir \( T \) en la expresión original: \( \frac{1.3}{5.2} \), que es aproximadamente 0.25 o \( \frac{1}{4} \). ¡Así que sí, tu respuesta es correcta!
