How do you turn a scale factor in to a decimal?

To convert a scale factor into a decimal, simply divide the numerator by the denominator if it is a fraction. For example, if the scale factor is 3:4, you would divide 3 by 4 to get 0.75. If the scale factor is already a whole number, you can express it as a decimal by adding a decimal point followed by zeros (e.g., 2 becomes 2.0). This conversion allows for easier calculations and comparisons.
