According to Ohm's Law, the correct equation that relates voltage (V), current (I), and resistance (R) is:

[tex]\[ V = IR \][/tex]

This means that voltage equals the product of current and resistance.

Let's analyze the given options:

1. [tex]\( V = IR \)[/tex]
- This is the fundamental equation of Ohm's Law and it correctly represents the relationship between voltage, current, and resistance.

2. [tex]\( I = \frac{R}{V} \)[/tex]
- This equation suggests that current equals resistance divided by voltage, which is incorrect.

3. [tex]\( R = \frac{I}{V} \)[/tex]
- This equation suggests that resistance equals current divided by voltage, which is also incorrect.

4. [tex]\( R = IV \)[/tex]
- This equation suggests that resistance equals current multiplied by voltage, which is incorrect.

Therefore, the correct equation according to Ohm's Law is:

[tex]\[ V = IR \][/tex]

So, the correct choice is the first one.

The answer to the question is:

[tex]\[ 1 \][/tex]
