Question

A 10 ft fence is 8 in .long on the scale drawing. What is the scale drawing?

Answer 1

Think of it this way:

10 (ft) -------- 120 (in) -> 10 ft is equal to 120 in
x ------- 8 (in) -> x ft is equal to 8 in

so then all you have to do is find the value of x, you do this by multiplying 10*8 (=80) and dividing that by 120, which as a fraction will give you

80
-------, you can even simplify (divide both terms by 10 [to remove the 0's], 120 then divide them again by 4) this and it will give you the final result of 2/3. That will be the scale.

Answer 2

To find scale we have to provide common unit, so inches.
10 foot = 120 inch becauyse 1 foot = 12 inch so
10foot*12=120 ich
Now
8 inch in drawing is 120 in real, so the scale is 8:120
