To find a fraction that is equivalent to 3/5, we can multiply or divide both the numerator and denominator by the same number.

For example, if we multiply both the numerator and denominator by 2, we get:

(3 * 2) / (5 * 2) = 6/10

So, 6/10 is equivalent to 3/5.

Similarly, if we divide both the numerator and denominator by 3, we get:

(3 / 3) / (5 / 3) = 1/ (5/3) = 3/5

So, 1/ (5/3) is also equivalent to 3/5.
