Discussion Overview

The discussion revolves around calculating the total weight of food items sold based on the weight of beans sold and their corresponding angle in a pie chart representation. Participants explore the relationships between the weights of different food items and their angles, seeking a method to simplify the calculations.

Discussion Character

  • Homework-related
  • Mathematical reasoning
  • Exploratory

Main Points Raised

  • One participant asks how to calculate the total weight of food sold given that 425 kg of beans corresponds to a certain angle in a pie chart.
  • Another participant questions how to determine the degrees associated with the beans and suggests using the degree of portion.
  • Participants discuss the total degrees in a pie chart, noting that they sum to 360 degrees.
  • One participant calculates the ratio of beans to sugar based on their respective angles (85° for beans and 80° for sugar) and attempts to find the amount of sugar corresponding to 425 kg of beans.
  • There is confusion regarding the calculated amount of sugar, with one participant noting that the found value exceeds the weight of beans, prompting a reevaluation of the calculation.
  • A subsequent participant proposes a corrected calculation for sugar based on the ratio, suggesting that 400 kg is the correct amount.
  • Participants discuss the need for a shortcut to calculate the total weight of all ingredients without calculating each item individually, leading to a formula involving the total degrees and the weight of beans.

Areas of Agreement / Disagreement

Participants express varying levels of confidence in their calculations, with some agreeing on the correctness of the final calculations while others seek clarification and simplification. The discussion includes both agreement on certain calculations and ongoing uncertainty regarding the overall approach.

Contextual Notes

Participants rely on the assumption that the angles in the pie chart accurately represent the proportions of each food item, but there is uncertainty about the calculations and the relationships between the weights and angles.

hello guys..

i need someone could help me out this problem below,

on the side is sale of food diagram.
if bean is sold 425 Kg, so how many all item food that sold out?

Hi!

How many degrees in the bean pie? (Wondering)

hi Serena...

that's my problem, how to looking for degree of bean..
i think use degree of portion, but how to make it?

There's 360 degrees in total. So all pies together must sum up to 360...

You've got 85 degrees for the beans. Good! (Smile)

What are you trying to find in your next step?I think we should try to find the amount of sugar...

Since sugar is 80 degrees, the ratio of beans to sugar is 85 / 80.
We know there is 425 kg of beans, and we want to know the amount of sugar.
Their ratio has to be the same, so:

425 kg of bean / amount of sugar = 85 / 80.

What would the amount of sugar be? (Wondering)

You almost got it.

But let's see... the pie of sugar (80°) is smaller than the pie of beans (85°).
You found 451.56 kg of sugar... but that is greater than the 425 kg of beans.
That can't be right! (Shake)

What should be changed to make it right? (Wondering)

how about

=80/85*425 Kg = 400 Kg, It's true?

Yep. It is. (Nod)

What about the rice and the corn?

hi..Serena..

please, see my answer..it's all true?

and how to find shortcut this problem, not calculation one by one item...

Yep. All true. (Nod)

The complete pie contains 360 degrees.
To find the total of all ingredients you can do:

Total = 360/85 x 425 kg = 1800 kg
