Answer:
Step-by-step explanation:
Let x represent the number of pennies that Al had initially.
He agreed to give six thirteenths of his pennies to Bev. It means that the number of pennies that he gave to Bev is 6/13 × x = 6x/13
if she would give six thirteenths of what she got from Al to Carl, it means that the number of pennies that Carl received is 6/13 × 6x/13 = 36x/169
if Carl in turn would give six thirteenths of what he got from Bev to Dani and Dani received 2376 pennies, it means that
6/13 × 36x/169 = 2376
216x/2179 = 2376
216x = 2376 × 2179
216x = 5220072
x = 5220072/216
x = 24167
AI had 24167 pennies initially
X y
1 = 4
2 = 8
3 = 12
4 = 16
X = pounds
y = price
The number of people increased by 2.
This means as a ratio it is now 6/4 as many as originally planned.
6/4 can be reduced to 3/2.
The time and the number of people are inversely proportional, so the food would last 2/3 ( inverse is flipping the original ratio over) the original length of time.
This means the length of time the food lasts is reduced by 1/3, which is 33.3%
Se pueden concluir dos posibilidades para cada bolsa y toda la colección:
- 4 balones rojos y un balón azul, lo cual lleva a 16 balones rojos y 4 balones azules.
- 3 balones rojos y dos balones azules, lo cual lleva a 12 balones rojos y 8 balones azules.
<h3>¿Cuántos balones rojos tiene Roberto en las cuatro bolsas?</h3>
En este problema conocemos que Roberto tiene 20 balones entre azules y rojos y que existen más balones rojos que azules. Puesto que los balones son objetos que pueden contarse, los datos a buscar deben ser números enteros y positivos y que están distribuidos equitativamente en cuatro bolsas. Entonces las cantidades de balones por bolsa son:
x = 20 / 4
x = 5
Existen 5 balones por bolsa y bajo la consideración de que existen balones azules, que cada bolsa tienen la misma proporción de balones rojos a azules y que los balones rojos son más que los balones azules, se pueden concluir dos posibilidades para cada bolsa:
- 4 balones rojos y un balón azul, lo cual lleva a 16 balones rojos y 4 balones azules.
- 3 balones rojos y dos balones azules, lo cual lleva a 12 balones rojos y 8 balones azules.
