Answer:

31.5 kg om

Step-by-step explanation:

Esto se calcula como:

12 trabajadores = 42 kg

9 trabajadores = x kg

Cruz Mulitiply

12 trabajadores × x kg = 9 trabajadores × 42 kg

x kg = 9 trabajadores × 42 kg / 12 trabajadores

x kg = 31.5 kg

Por tanto, 9 trabajadores consumirán 31.5 kg de arroz al mismo tiempo.

Answer:

31.5 kg de arroz consumirán 9 obreros en el mismo tiempo.

Step-by-step explanation:

Dos cantidades son directamente proporcionales si cuando una de ellas se multiplica o se divide por un número, la otra se multiplica o se divide por el mismo número.

La “regla de tres” es un procedimiento que se aplica para resolver problemas de proporcionalidad en el que se conocen tres de los cuatro datos que componen las proporciones y se requiere calcular el cuarto.

En este caso aplicamos la siguiente regla de tres: si 12 obreros consumen 42 kg, 9 obreros ¿Cuántos kg de arroz consumirán?

kg de arroz=\frac{9 obreso*42 kg}{12 obreros}

kg de arroz= 31.5

<u><em>31.5 kg de arroz consumirán 9 obreros en el mismo tiempo.</em></u>
