Answer:
[tex]\frac{1}{90}[/tex]
Step-by-step explanation:
Before calculating the scale we require the dimensions to be in the same units.
Using the conversion
1 yard = 3 ft and
1 foot = 12 inches, then
5 yards = 5 × 3 × 12 = 180 inches
The scale is then
2 in : 180 in ← divide both quantities by 2
= 1 : 90
= [tex]\frac{1}{90}[/tex]
