Discussion Overview

The discussion revolves around creating a real-life word problem that incorporates the mathematical expression 1/2 x 7/8. Participants explore how to formulate a relatable scenario, illustrate it with a diagram, and evaluate the expression.

Discussion Character

  • Homework-related
  • Exploratory

Main Points Raised

  • One participant suggests using a pizza-sharing scenario to illustrate the problem, where one person takes a slice and the remainder is shared.
  • Another participant confirms the pizza example and provides a breakdown of the remaining pizza after one slice is taken, leading to the calculation of 1/2 * 7/8.
  • There is a request for a diagram to visually represent the problem, specifically asking if it should show eight pieces with seven colored to indicate what remains after one slice is taken.
  • A follow-up response agrees with the diagram suggestion and adds that the remaining pieces should be divided to show how they are shared between two people.

Areas of Agreement / Disagreement

Participants generally agree on using the pizza example and the method of illustrating the problem, but the specifics of the diagram and its representation are still being refined.

Contextual Notes

The discussion includes assumptions about the audience's familiarity with fractions and the context of sharing food, which may not be universally applicable. The exact details of the diagram are not fully resolved.

Who May Find This Useful

Parents, educators, and students looking for practical examples of fraction multiplication in real-life contexts.

Hi All,
My child has a problem that I can't help him to understand.
It will be highly appreciated if I could find a solution for this problem:
A studnet in answering a word problem wrote 1/2x7/8
a- Write a "real life" word problem for which 1/2x7/8 is part of the working.
b- Draw a diagram to illustrate 1/2 x 7/8
c- Evaluate 1/2x 7/8 "which I think this the easiest one"

Thank you in advance

Why don't you just do a pizza example. It's easy to understand and easy to show graphically.

Allan, Bob and Chuck buy a large pizza to share. Allan isn't very hungry and only wants one slice consisting of 1/8th of the total pizza. Bob and Chuck decide to share the remainder evenly between them.

1 - 1/8 = 7/8 remains after Allan takes his slice.

1/2 * 7/8 = 7/16 is what Bob and Chuck each get.
 
Thank you so much
What about the diagram
Is it eight pieces, then color 7 out of 8

Yes, and then show the 7 remaining pieces split into two equal parts by dividing at least one of them in two (making them each 1/16th).
