abraham needs one half of a point to get an A- in math.What rational numbers can be used to represent the number of points needed for abraham to get an A-

The rational numbers that can be used to represent the number of points needed for Abraham to get an A- are:

1/2, 2/4, 3/6, 4/8, 5/10, and so on.

These fractions all represent half of a point, which is what Abraham needs for an A-.

To find the rational numbers that can represent the number of points needed for Abraham to get an A-, we can consider fractions where the numerator is 1 (representing the half point needed) and the denominator is greater than or equal to 2 (to ensure it is rational).

Here are a few examples of rational numbers that can be used:

1/2
2/4
3/6
4/8
5/10
...
n/2n

So, any fraction in the form of n/2n would represent the number of points needed for Abraham to get an A-, where n is a positive integer.
