Answer:A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object. If the scale factor is a whole number, the copy will be larger. If the scale factor is a fraction, the copy will be smaller.
Step-by-step explanation: To find the scale factor, you first decide which direction you are scaling:
Scale Up (smaller to larger) = larger measurement / smaller measurement
Scale Down (larger to smaller) = smaller measurement / larger measurement
The scale factor for scaling up is a ratio greater than 1.
The scale factor for scaling down is a ratio less than 1.
