Sagot :
Answer: 81
Step-by-step explanation: divided 135 bultos entre 15 bancas, te da 9, entonces 9 x 9 son 81
Tenemos un problema simple sobre algebra.
Encontraremos que para constrir 9 bancas se necesitan 81 bultos de cemento.
La información dada es:
Se necesitan 135 bultos de cemento para construir 15 bancas.
Entonces la cantidad de bultos que se necesitan para cada banca está dada por el cociente entre la cantidad de bultos usados y la cantidad de bancas que salen de eso.
Esto es:
135/15 = 9
Es decir cada banca necesita 9 bultos de cemento.
Por lo tanto, para construir 9 bancas se necesitaran 9 veces 9 bultos de cemento:
9×9 = 81 bultos de cemento.
