To find the extremes of a proportion, we need to identify the first and the last terms in the given proportion. The proportion in question is:
[tex]\[
\frac{3}{4} = \frac{6}{8}
\][/tex]
In any given proportion written in the form [tex]\(\frac{a}{b} = \frac{c}{d}\)[/tex], the extremes are the first term [tex]\(a\)[/tex] and the last term [tex]\(d\)[/tex].
In this case:
- The first term ([tex]\(a\)[/tex]) is 3.
- The last term ([tex]\(d\)[/tex]) is 8.
Therefore, the extremes of the proportion [tex]\(\frac{3}{4} = \frac{6}{8}\)[/tex] are 3 and 8.
So, the correct answer is:
B. 3 and 8.
