Question

Tell whether each scale reduces enlarges or preserves the size of an actual object

Answer 1

1m to 25 cm is reduces
8 in to 1 ft is enlarges
12 in to 1 ft is preserves

Answer 2

Given:

1 m : 25 cm

8 in : 1 ft

12 in : 1 ft

 

First, we convert each variable given on the right:

 

1 m : 0.25 m (this means that 1 meter is made to represent 25 cm)

8 in : 12 feet (this means that 8 in is made to represent 1 feet)

12 in : 12 in (this means that 12 in is made to represent 1 feet)

 

After converting the variables, we can now know if the ratios are enlargement, reduction or preservation. Therefore:

1 m : 25 cm = Enlarge

8 in : 12 feet = Reduce
12 in = 1 ft = Preserve
