would the scale factor 7/2 reduce, enlarge, or preserve?

4/5 will reduce and 7/2 will enlarge.

Step-by-step explanation:

Ok, a scale factor is a number that can affect a given quantity, suppose the length of a segment, by multiplicating it.

Now, if the scale factor is greater than one, you will be doing a dilatation (this means that the length is increased)

If the scale factor is less than one, you will be doing a contraction (the length will be decreased)

If the scale factor is 1, you are preserving, this means that the scale factor = 1 does not affect the system.

now, we have:

4/5) here, because the numerator is smaller than the denominator we know that the fraction 4/5 must be smaller than one, so this scale factor will reduce.

7/2) Here we have that the numerator is greater than the denominator, so this number is greater than one, then this scale factor will enlarge
