how many eighth notes are needed to equal the duration of a half note? 2 4 6 8

Explanation:

Step1: Recall note - value relationships

In music, a half - note has a duration of 2 beats. An eighth - note has a duration of $\frac{1}{2}$ beat.

Step2: Calculate the number of eighth - notes

To find out how many eighth - notes equal the duration of a half - note, we divide the duration of the half - note by the duration of an eighth - note. Let $n$ be the number of eighth - notes. Then $n=\frac{2}{\frac{1}{2}}$. Using the rule of dividing by a fraction ($a\div\frac{b}{c}=a\times\frac{c}{b}$), we have $n = 2\times2=4$.
