If I am photocopying a rectangle that is 8 cm x 10 cm what scale factor do I use if I wanted to become 16 cm x 20 cm?
To determine the scale factor for enlarging a rectangle from 8 cm x 10 cm to 16 cm x 20 cm, divide the dimensions of the larger rectangle by the dimensions of the smaller rectangle. For the width, 16 cm ÷ 8 cm = 2, and for the height, 20 cm ÷ 10 cm = 2. Therefore, the scale factor you would use is 2.
What is the definition of scale factor?
The scale factor between two similar shapes is the ratio of the dimensions of one (often the smaller) compared with the dimension of the other (the larger).
How can you find the scale factor from a larger figure to the smaller figure using the scale factor from the smaller to larger figure?
Take the 'reciprocal' of the given scale factor to go the other way. The 'reciprocal' of a number is 1/(the number). 3 ==> 1/3 5 ==> 1/5 1/7 ==> 7 2/3 ==> 3/2 etc.

How can you find the scale factor from a smaller figure to the larger figure using the scale factor?
The two scale factors are reciprocals of one another.
How do you find a scale factor of a triangle?
To find the scale factor of two triangles, look first for one pair of corresponding sides--one side from the smaller triangle and the corresponding side from the larger triangle. Divide the larger side length by the smaller side length, and that quotient is your scale factor.

What is the scale factor of spheres with a radius of 12 and 4?
Assuming the smaller sphere is the image of the larger sphere after transformation (based on the order of the radii): the scale factor is 4/12 = 1/3

Abe acd find the scale factor?
To find the scale factor, you need to compare the corresponding sides of two similar figures. The scale factor is calculated by dividing the length of a side on the larger figure by the length of the corresponding side on the smaller figure. For example, if the larger figure has a side length of 8 units and the corresponding side on the smaller figure is 2 units, the scale factor would be 8 divided by 2, which equals 4.

How do you find the scale factor from a large rectangle to a small rectangle?
If you know one of the sides of both the rectangles than you just divide them by one another to find the scale factor.

Does a scale show measurement of a smaller distance that represents a larger distance?
Yes, but a scale can also be used to show a smaller distance by using a bigger distance (i.e. the opposite of the above). For example, imagine we were drawing a representation of something really small like the structure of an atom. If we wanted to draw this accurately we would have to use a scale which uses a larger distance to represent a smaller one.
