The fractional part of the rabbit population not in the two states is \(\frac{163}{238}\).

Solución

To determine the fractional part of the rabbit population **not** living in the two specified states, follow these steps: 1. **Identify the Fractions in the Two States:** - **State 1:** \(\frac{1}{34}\) of all rabbits. - **State 2:** \(\frac{2}{7}\) of all rabbits. 2. **Calculate the Combined Fraction in Both States:** \[ \frac{1}{34} + \frac{2}{7} \] To add these fractions, find a common denominator. The least common multiple (LCM) of 34 and 7 is 238. \[ \frac{1}{34} = \frac{7}{238} \quad \text{and} \quad \frac{2}{7} = \frac{68}{238} \] \[ \frac{7}{238} + \frac{68}{238} = \frac{75}{238} \] 3. **Determine the Fraction Not in Either State:** Subtract the combined fraction from the whole population (which is \(1\) or \(\frac{238}{238}\)). \[ 1 - \frac{75}{238} = \frac{238}{238} - \frac{75}{238} = \frac{163}{238} \] 4. **Simplify the Fraction (if possible):** - **163** is a prime number. - **238** factors into \(2 \times 7 \times 17\). Since there are no common factors between **163** and **238**, the fraction is already in its simplest form. **Final Answer:** \[ \frac{163}{238} \]

To find the total fractional part of the rabbit population not in the two states, we start by summing the fractions of rabbits in each state: \[ \frac{1}{34} + \frac{2}{7} \] To add these, we need a common denominator. The least common multiple of 34 and 7 is 238. Converting each fraction: \[ \frac{1}{34} = \frac{7}{238}, \quad \text{and} \quad \frac{2}{7} = \frac{68}{238} \] Now, add the fractions: \[ \frac{7}{238} + \frac{68}{238} = \frac{75}{238} \] The total fraction of rabbits in these two states is \(\frac{75}{238}\). To find the part of the rabbit population not in those two states, we subtract this from the whole: \[ 1 - \frac{75}{238} = \frac{238 - 75}{238} = \frac{163}{238} \] Thus, the total fractional part of the rabbit population not living in the two states is: \[ \frac{163}{238} \] So the answer to your question is \( \frac{163}{238} \).
