Fractions are ratio of two integers. The museum has a side length of 20 inches.
<h3>Ratios and proportions</h3>
Fractions are written as a ratio of two integers. The use of scale factors is important in diminishing and enlarging a figure or object.
Given the following parameters
Measure of the side base of the museum = 60m
If the scale factor os the side base is 3 inches to 18m, hence the side length in inches is given below:
3in = 18meters
x = 60meters
<u>Take the ratios</u>
3/x = 18/60
18x = 3(60)
18x =180
x = 180/18
x = 10inches
Hence the side length of the museum in inches is 10 inches.
