Answer:
scale factor 1.5 or 1 1/2
Step-by-step explanation:
15/2 is the same as 15÷2 and 15÷2=7.5
now we need to turn 5 into 7.5
to do that lets multiply by 5(1.5) or 5(1+0.5) (the 5 on the outside of the parenthesis means to multiply it by all on the inside)
and we get 5+2.5 or 7.5
so the scale factor is 1.5 or 1 1/2
