Step 1: Simplifying the Expression
When dividing fractions, the rule is to multiply by the reciprocal of the divisor. So, let’s go one division at a time:

15÷15=1\frac{1}{5} \div \frac{1}{5} = 151​÷51​=1

Why? Because any number divided by itself is 1.

Step 2: The Next Division
Now, we are left with:

1÷151 \div \frac{1}{5}1÷51

Using the reciprocal rule again:

1÷15=1×5=51 \div \frac{1}{5} = 1 \times 5 = 51÷51​=1×5=5

Step 3: The Final Division
Finally, we have:

5÷155 \div \frac{1}{5}5÷51​

Again, applying the rule of reciprocals:

5×5=255 \times 5 = 255×5=25

So, the correct answer is 25! 🎉

c) 25 is the right choice.
