Problema Solution
A machine grinds 3/6 pounds of coffee beans in 3/5 second.What is the rate in pounds per second that the machine grinds coffee beans?
Answer provided by our tutors
3/6 pounds => 3/5 second
3/6 x 1/3 => 3/5 x 1/3 (both sides times 1/3 to see 1/5 second can grinds how many pounds of coffee)
1/6 x 5 => 1/5 x 5 (both sides times 5 to get 1 second)
5/6 => 1 second
Hence, 1 second can grind 5/6 pounds of coffee
