The rational number that represents the scenario of 14 programming errors for every 56 programmers is 14/56.
A rational number is any number that can be written as a fraction, where the numerator and denominator are both integers (whole numbers).
Out of the given options, the rational number is:
- The fraction with numerator 8 and denominator square root of 8.
So, the answer is the option:
the fraction with numerator 8 and denominator square root of 8.
To determine which of the given options is a rational number, we need to understand what a rational number is. A rational number is a number that can be expressed as a fraction, where the numerator and denominator are both integers.
Let's evaluate each option to see if it meets the criteria:
1. 7 - √: This is an irrational number because it includes the square root of 7, which cannot be expressed as a fraction.
2. √7: This is also an irrational number because it is the square root of 7, which cannot be expressed as a fraction.
3. 88√: This is an irrational number because it includes the square root of 8, which cannot be expressed as a fraction.
4. 7.8: This is a rational number because it can be expressed as the fraction 78/10, where both the numerator and denominator are integers.
Therefore, the only option that is a rational number is 7.8.
