A counterexample for a conjecture is the statement that disproves a conjecture.

Step-by-step explanation:

To find : What is a counterexample for the conjecture?

Solution :

A conjecture is an educated guess but not yet proven. It is possible that next example shown the conjecture wrong.

How do i multiply fractions
Hatshy [7]
Best Answer:  <span> to multiply fractions you simply take the denominator of both fractions and multiply them, do the same to the numerator, and you have your answer.
ex.
2 5 10
-- * -- = ----
4 8 32

then, of course, you would need to simplify.

so the answer is

10(/2) 5
-------- = -----
32(/2) 16


To multiply mixed numbers, you need to convert them to improper fractions, multiply and then convert them back to a mixed number. For example:
2 1/2 x 5 1/3 = 5/2 x 16 /3

numerator 5 x 16 = 80 denominator 2 x 3 = 6

so now you convert 80/6 into a mixed number

80 / 6 = 13 and 2/6 or, reduced, 13 1/3. </span>

Which shows the expressions rewritten with the least common denominator?
baherus [9]

Answer:

  D.  (14x-4)/(8x^2) and (x^2-x)/(8x^2)

Step-by-step explanation:

The least common denominator will be 8x^2, the product of 2 and x to the highest of their powers in either of the denominators.

  \left\{\dfrac{7x-2}{4x^2},\ \dfrac{x-1}{8x}\right\}=\left\{\dfrac{7x-2}{4x^2}\cdot\dfrac{2}{2},\ \dfrac{x-1}{8x}\cdot\dfrac{x}{x}\right\}\\\\=\left\{\dfrac{14x-4}{8x^2},\ \dfrac{x^2-x}{8x^2}\right\}
