math - kelvin today at 2:22pm
i had the this idea but i shocked when i saw the answer so if there is another idea plz help me out
The answer from the book is 280 kg
56/16 = 3.5 kg per person per week
3.5 * 24 = 84 kg for 24 persons for one week
84 * 4 = 336 kg for 24 people for 4 weeks
Well, if 16 people need 56 kg of rice in 1 week, let's calculate how much rice one person would need in 1 week.
56 kg/16 people = 3.5 kg/person/week
Now, we can calculate how much rice 24 people would need in 1 week.
3.5 kg/person/week x 24 people = 84 kg/week
Since we need to calculate the amount of rice needed for 4 weeks, we simply multiply the weekly amount by 4.
84 kg/week x 4 weeks = 336 kg
So, according to my calculations, 24 people would need 336 kg of rice in four weeks. Hope that helps!
To find out how much rice will be needed by 24 persons in four weeks, we can follow the steps below:
Step 1: Calculate the amount of rice needed per person per week.
56 kg of rice is needed for 16 persons in 1 week.
So, for 1 person, the amount of rice needed in 1 week is:
56 kg / 16 persons = 3.5 kg/person/week
Step 2: Calculate the total amount of rice needed by 24 persons in 1 week.
To find the amount of rice needed by 24 persons in 1 week, multiply the rice needed per person per week (3.5 kg) by the number of persons:
3.5 kg/person/week * 24 persons = 84 kg/week
Step 3: Calculate the total amount of rice needed by 24 persons in four weeks.
To find the total amount of rice needed by 24 persons in four weeks, multiply the amount of rice needed per week by the number of weeks:
84 kg/week * 4 weeks = 336 kg
So, the final answer is 336 kg of rice will be needed by 24 persons in four weeks.
To calculate the amount of rice needed by 24 persons in four weeks, you can use the proportional relationship between the number of persons and the amount of rice.
Given:
- 16 persons need 56 kg of rice in 1 week
To find the amount of rice needed by 24 persons in four weeks, you can set up a proportion:
Let "x" be the amount of rice needed by 24 persons in four weeks.
We can set up the following proportion:
16 persons : 24 persons = 56 kg : x
To solve this, you can cross-multiply and solve for "x":
16 * x = 24 * 56
Now simplify:
16x = 1344
Divide both sides by 16 to isolate "x":
x = 1344 / 16
x = 84 kg
Therefore, the amount of rice needed by 24 persons in four weeks is 84 kg.
It seems like your calculation is correct, so the answer you have calculated (24*(56/16)*4 = 84 kg) is correct, not the answer provided in the book.
