Primero, necesitamos que ambas fracciones tengan un denominador común para sumarlas. El mínimo común múltiplo de 9 y 20 es 180. Por lo tanto, convertimos las fracciones: \( \frac{7}{9} = \frac{7 \times 20}{9 \times 20} = \frac{140}{180} \) y \( \frac{8}{20} = \frac{8 \times 9}{20 \times 9} = \frac{72}{180} \). Ahora podemos sumar: \( \frac{140}{180} + \frac{72}{180} = \frac{212}{180} \). Simplificando, queda \( \frac{53}{45} \). Y ahí lo tienes, ¡una suma lista para ser celebrada!
