The distance between two points, a and b, on a number line is expressed as
la – bl. where a and b are rational numbers.
Think about locating a point halfway
between a and b on a number line. How can you
find the coordinate for such a point? Develop a
formula in terms of a and b that you can use to
find the coordinate. Your formula must work for
positive and negative values of a and b. Does
absolute value play a role in your formula? Why
or why not? Under what circumstances might
your formula be used in the real world? Explain

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
