Using specific examples, the unit rate can be obtained using equivalent ratio tables and fraction thus :
Table of equivalent ratios :
No of workers : ____ 2 ____ 4 ____ 6 ____ 8
Logs of wood cut: __ 4 ____ 8 ____12 ____16
To obtain the unit rate from the table :
Take the ratio of any pair of values ;
Hence, the unit rate is 2 logs of wood per worker.
Using the fractions :
2 worker = 4 logs of wood
1 worker = x
Cross multiply
2x = 4
x = 4/2
x = 2 logs of wood.
