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).
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Thread 'Imaginary Pythagorus'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
