What's an equation for 1/3?

Question

I want negatives and it has to be only like 2+2 not 2+2+2 and there needs to be fractions in it and it can not be very easy

Answer 1

Think about the sum of 1/2 + 1/4. In money that's 0.50 + 0.25 = 0.75, or 3/4 dollar.

1/2 + 1/4 = 3/4 because 1/2 can also be written 2/4, so the problem becomes 2/4 + 1/4 = 3/4

Try to do the same kind of thing with 1/3. Maybe you can change 1/3 into an equivalent fraction like we changed 1/2 into 2/4. Then you might be able to come up with an addition or subtraction problem that would give you an answer equivalent to 1/3.

Answer 2

J,

  This is a bit of an ambiguous question but let's try one approach:

What's an equation in 2 variables that equals 1/3?  I have added the bold wording.

Addition:  A + B = 1/3   Solution: A and B = 1/6  Check:  1/6 + 1/6 = 2/6 = 1/3

Multiplication:  A * B = 1/3  Solution:   A and B =1/Sqrt(3)

      Check:  {1/Sqrt(3)} * {1/Sqrt(3)} =    {1/Sqrt(3)}^2  = 1/3

Etc, Etc.  You can see that the questiooin is ambiguous because the operators are not defined and this leads to an infinite number of possibilities.

Check to see if you have written the question down precisely as asked.
