Step-by-step explanation:

Find a linear dimension of the image, such as a length, width, height, altitude, etc. Find the corresponding dimension in the original. Divide the length of the image by the original length.

Linear dimension in the image: A'B' = 6

Corresponding length in the original: AB = 3

divide image/original

scale factor = 6/3 = 2

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
