Final answer:
To divide a whole number by a fraction, convert the whole number to an improper fraction and multiply by the reciprocal of the fraction.
Step-by-step explanation:
To divide a whole number by a fraction, we can use the reciprocal or multiplicative inverse of the fraction. In this case, we want to divide 2 1/5 by 3/5. First, we convert the whole number to an improper fraction, which is 11/5. Then, we multiply 11/5 by the reciprocal of 3/5, which is 5/3. Multiplying fractions involves multiplying the numerators together and multiplying the denominators together. So, 11/5 ÷ 3/5 is equal to (11/5) × (5/3) = 55/15. This fraction can be simplified to 11/3.
