Given that [tex]$p$[/tex] is a positive number, [tex]$n$[/tex] is a negative number, and [tex]$|p|\ \textgreater \ |n|$[/tex], which of the following expressions has the greatest value?

A. [tex]\left|\frac{p-n}{p}\right|[/tex]
B. [tex]\left|\frac{p-n}{n}\right|[/tex]
C. [tex]\left|\frac{p+n}{p-n}\right|[/tex]
D. [tex]\left|\frac{p+n}{p}\right|[/tex]
E. [tex]\left|\frac{p+n}{n}\right|[/tex]



Answer :

To determine which expression among the given ones has the greatest value, let's evaluate each of them step-by-step using example values for [tex]\( p \)[/tex] and [tex]\( n \)[/tex] that meet the conditions: [tex]\( p \)[/tex] is positive, [tex]\( n \)[/tex] is negative, and [tex]\( |p| > |n| \)[/tex].

Let [tex]\( p = 10 \)[/tex] and [tex]\( n = -4 \)[/tex]. We will evaluate each expression:

1. [tex]\( F: \left|\frac{p - n}{p}\right| \)[/tex]
Substituting the values:
[tex]\[ F = \left|\frac{10 - (-4)}{10}\right| = \left|\frac{10 + 4}{10}\right| = \left|\frac{14}{10}\right| = 1.4 \][/tex]

2. [tex]\( G: \left|\frac{p - n}{n}\right| \)[/tex]
Substituting the values:
[tex]\[ G = \left|\frac{10 - (-4)}{-4}\right| = \left|\frac{10 + 4}{-4}\right| = \left|\frac{14}{-4}\right| = \left| -3.5 \right| = 3.5 \][/tex]

3. [tex]\( H: \left|\frac{p + n}{p - n}\right| \)[/tex]
Substituting the values:
[tex]\[ H = \left|\frac{10 + (-4)}{10 - (-4)}\right| = \left|\frac{10 - 4}{10 + 4}\right| = \left|\frac{6}{14}\right| = \left|\frac{3}{7}\right| \approx 0.42857 \][/tex]

4. [tex]\( J: \left|\frac{p + n}{p}\right| \)[/tex]
Substituting the values:
[tex]\[ J = \left|\frac{10 + (-4)}{10}\right| = \left|\frac{10 - 4}{10}\right| = \left|\frac{6}{10}\right| = 0.6 \][/tex]

5. [tex]\( K: \left|\frac{p + n}{n}\right| \)[/tex]
Substituting the values:
[tex]\[ K = \left|\frac{10 + (-4)}{-4}\right| = \left|\frac{10 - 4}{-4}\right| = \left|\frac{6}{-4}\right| = \left| -1.5 \right| = 1.5 \][/tex]

Now we compare the evaluated results:
- [tex]\( F = 1.4 \)[/tex]
- [tex]\( G = 3.5 \)[/tex]
- [tex]\( H \approx 0.42857 \)[/tex]
- [tex]\( J = 0.6 \)[/tex]
- [tex]\( K = 1.5 \)[/tex]

Among these values, the greatest value is [tex]\( G = 3.5 \)[/tex].

Therefore, the expression [tex]\( \left|\frac{p - n}{n}\right| \)[/tex] has the greatest value. Hence, the answer is:

[tex]\[ \boxed{\text{G}} \][/tex]
