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
