To determine the numerator in the fraction [tex]\(\frac{0}{78}\)[/tex], we need to recall the parts of a fraction. A fraction consists of two main components:
1. Numerator: This is the number above the fraction bar, representing the number of parts we have.
2. Denominator: This is the number below the fraction bar, representing the total number of equal parts the whole is divided into.
Given the fraction [tex]\(\frac{0}{78}\)[/tex]:
- The numerator is the number above the fraction bar, which in this case is 0.
- The denominator is the number below the fraction bar, which in this case is 78.
Therefore, the numerator in the fraction [tex]\(\frac{0}{78}\)[/tex] is [tex]\( \boxed{0} \)[/tex].
