AI Thread Summary
A word problem involving the multiplication of fractions 1/2 x 7/8 can be illustrated using a pizza-sharing scenario. In this example, three friends share a large pizza, where one friend takes a slice of 1/8, leaving 7/8 for the others. Bob and Chuck then divide the remaining pizza, resulting in each getting 1/2 of 7/8, which equals 7/16. To visually represent this, a diagram can show the pizza divided into eight slices, with seven slices colored to indicate what remains. This approach effectively demonstrates the concept of fraction multiplication in a relatable context.

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).
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
