Question

If my original drawing is 1.75 inches and the scaled drawing is 0.75 what is the scale factor?

Answer 1

• The scale factor is 3/7

Explanation:

As per definition, the scale factor is:

The ratio between corresponding measurements of an object and a representation of that object.

• 
  `k = d_n/d_o`

Where, k - scale factor,
`d_n` - dimension of the new shape,
`d_o` - dimension of the original shape.

The scale factor in our case is:

• k = 0.75/1.75 = (3*0.25)/(7*0.25) = 3/7
