Question

como se saca 80/50 + 54/90 =​

Answer 1

Respuesta:

R// 11/5 ó 2.2

Explicación:

Suma de fracciones

$\frac{80}{50} + \frac{54}{90} = \frac{(90 \times 80) + (50 \times 54)}{(50 \times 90)} = \\ \frac{(7200) + (2700)}{4500} = \frac{9900}{4500} = \frac{99}{45} = \frac{33}{15} = \\ \frac{11}{5} = 2.2$

$r = \frac{80}{50} + \frac{54}{90} = \frac{11}{5} = 2.2$
