Step 1

Let's write down these fractions:

From here, we can see that these fractions have unlike denominators.

Step 2

Since the denominators are not the same, we must make them the same before we are able to subtract them. To do so, we can use the ideas behind Equivalent Fractions.

To find the equivalent fractions, we can multiply ³/₅ with the other fraction's denominator and vice versa. By doing so, both fractions will have like denominators. This is shown below:

Step 3

Now, both fraction have like denominators. We can proceed by adding these fractions. This will result in the fraction ⁴/₁₅.

Step 4

Finally, we get the fraction, ⁴/₁₅. Clearly, the answer is C.
