Question

I need help for this question

Answer 1

A scale factor of 4in to 5in should be used

Explanation:

Given

`Original\ Measurement = 4.5\ in`

`Scale\ Measurement = 3.6\ in`

Required

Determine the scale to use

The scale to use can be represented as:

`Scale = Scale\ Measurement : Original\ Measurement`

This gives:

`Scale = 3.6\ in : 4.5\ in`

Divide by 0.9

`Scale = (3.6)/(0.9)\ in : (4.5)/(0..9)\ in`

`Scale = (3.6)/(0.9) : (4.5)/(0.9)`

`Scale = 4 : 5`
