To convert 7 cm to inches, you will need to use the conversion factor of 1 inch = 2.54 cm. This means that for every 2.54 cm, there is 1 inch. With that in mind, here are the steps to convert from centimeters (cm) to inches (in):

Step 1: Write down the given value

We are given 7 cm, so we will start with writing down 7 cm.

Step 2: Set up the conversion factor

As mentioned earlier, 1 inch = 2.54 cm. We will set up the conversion factor as (1 inch / 2.54 cm). This will help us to cancel out the cm unit and convert to inches.

Step 3: Set up the conversion equation

To convert, we will multiply 7 cm by the conversion factor we just set up. This will give us the following equation: 7 cm x (1 inch / 2.54 cm).

Step 4: Cancel out the common unit

In our equation, we have cm in both the numerator and denominator. This means they will cancel out, leaving us with inches as our unit of measurement.

Step 5: Solve for the unknown value

We can now solve our equation by multiplying 7 x 1 = 7. This tells us that 7 cm is equal to 7 inches.

Step 6: Write the final answer

Our final answer is 7 inches. This means that 7 cm is equal to 7 inches.

In conclusion, to convert from cm to inches, you need to divide the given value by 2.54. Keep in mind that this method can be used for any conversion from cm to any unit of length, as long as you use the correct conversion factor.
