2 x 2/5 = 5/2 + 5/2

1 x 4/7 = 1/7 + 1/7 + 1/7 + 1/7

6 x 1/3 = 1/6 + 1/6 + 1/6

To convert a multiplication problem involving a whole number and a fraction into an addition problem, you can express the multiplication as repeated addition of the fraction.

Let's analyze each option:

  1. 2 x 2/5 = 5/2 + 5/2
    This is incorrect because it incorrectly represents the multiplication.

  2. 1 x 4/7 = 1/7 + 1/7 + 1/7 + 1/7
    This is incorrect because it incorrectly represents the value of 1 multiplied by the fraction.

  3. 6 x 1/3 = 1/6 + 1/6 + 1/6
    This is incorrect because the sum of three 1/6 does not equal 6 x 1/3.

  4. 3 x 3/5 = 3/5 + 3/5 + 3/5
    This is correct! It represents the multiplication accurately as repeated addition.

Therefore, the correct choice is: 3 x 3/5 = 3/5 + 3/5 + 3/5.
