English Measurement
English Measurement is based on fractions of an inch.
Each mark on a ruler represents 1/16 of an inch.
Also note that (“) represents inches and (‘) represents feet.

English Measurement
An important rule when reading English linear measurements is to remember how to reduce fractions.
For example, 1 inch equals 16/16.
(16 divided by 16 equals 1) 6

English Measurement
For example…
4/16 = ¼”
12/16 = ¾”
Some students may need the reduction of fractions explained. (For example: 4/16 becomes ¼, because 4 and 16 are both divisible by 4)
0/16 = 0”
8/16 = ½” 7
