What scale factor value times 6 ft would result in 5 ft? Consider the variable equation with x as the scale factor:
6 • x = 5
After isolating x, what do you get as the scale factor?
If the scale factor to change from B to A is just the reverse to change the shape back to its original form,
what would it be? Create an expression like above if necessary.
The scale factors are reciprocals.
