1:24
1:12
1:4
1:48

Answer 1

Do you know proportions?

Answer 2

For example, you are given something like 3:48, first note that scale is always 1 to something. Take something as x.

\( \color{Black}{\Rightarrow 3:48=1:x}\)

Answer 3

Here you'd do this proportion - \(2:8=1:x\)

Answer 4

The RHS would be the scale.
