The correct Answer is:
To find the reciprocal of a number or a fraction, we simply flip the numerator and the denominator. Let's solve the given question step by step. ### Step-by-Step Solution: **(i) Find the reciprocal of `3/7`:** 1. The fraction is `3/7`. 2. To find the reciprocal, we switch the numerator and the denominator. 3. Therefore, the reciprocal of `3/7` is `7/3`. **(ii) Find the reciprocal of `1/5`:** 1. The fraction is `1/5`. 2. To find the reciprocal, we switch the numerator and the denominator. 3. Therefore, the reciprocal of `1/5` is `5/1`, which can also be written as `5`. **(iii) Find the reciprocal of `6`:** 1. The number `6` can be expressed as a fraction: `6/1`. 2. To find the reciprocal, we switch the numerator and the denominator. 3. Therefore, the reciprocal of `6` is `1/6`. **(iv) Find the reciprocal of `3 5/8`:** 1. First, convert the mixed number `3 5/8` into an improper fraction. - Multiply the whole number `3` by the denominator `8`: `3 * 8 = 24`. - Add the numerator `5`: `24 + 5 = 29`. - So, `3 5/8` becomes `29/8`. 2. To find the reciprocal, we switch the numerator and the denominator. 3. Therefore, the reciprocal of `29/8` is `8/29`. ### Final Answers: 1. Reciprocal of `3/7` is `7/3`. 2. Reciprocal of `1/5` is `5`. 3. Reciprocal of `6` is `1/6`. 4. Reciprocal of `3 5/8` is `8/29`.
