__SCALE__Ø is a comparison of two objects; the actual size and its diagram

Ø Scale can be expressed as a ratio

__(__, as a fraction, as a percent, in words or as a diagram.**most common**)A scale of 1:50 means that 1 unit on the diagram is equal to 50 units of the actual object.

__SCALE DIAGRAM__Ø Is similar or the actual or object. It maintain proportion, the diagram may be longer or smaller than the actual object.

__There are two ways to find a missing length of proportion:__**Use scale to determine the Actual Length of an Object.**

__Example One:__

For a scale of 1:14 and a diagram measuring 5.5cm set the proportion.

__Example One:__For a scale of 1:14 and a diagram measuring 5.5cm set the proportion.

x=77cm

Because it is easy to find the relationship of 1 to 5.5 it easy to find x, simply multiply 14 by 5.5 to find x=77cm- So the actual object is 77cm. x= 5.5(14)

x=77cm

Because it is easy to find the relationship of 1 to 5.5 it easy to find x, simply multiply 14 by 5.5 to find x=77cm- So the actual object is 77cm.

**Use Measurement to find Scale**

__Example Two:__An object measures has an actual measurement of 120 km. What is the scale?

So the scale is 1:2400000cm or 1:24km
