Answer:
One or unity or 1
Explanation:
For example,
1 min =60 s
If we divide each side of the equation by 1 min, we get
[tex]1 = \dfrac{\text{60 s}}{\text{1 min}}[/tex]
If we divide each side of the equation by 60 s, we get
[tex]\dfrac{\text{1 min}}{\text{60 s}} = 1\\\\\text{Thus, both conversion factors, $\dfrac{\text{60 s}}{\text{1 min}}$ and $\dfrac{\text{1 min}}{\text{60 s}}$, equal 1.}[/tex]
