Given the statement:
A fertilizer covers 5/6 square foot in 1/4 hour. The unit rate is square feet per hour.
Find the unit rate.
Solution:
In order to determine the unit rate we simply needed to divide 5/6 by ¼. Hence we must take note that in dividing a number with a fraction, we instead take the reciprocal of the fraction then multiply it to the other value. In our case the reciprocal of ¼ is 4/1 , hence we multiply 4/1 to 5/6.
= 5/6 / ¼
= (5/6)(4/1)
= 20/6 ft^2 per hr
= 10/3 ft^2 per hr
Final answer:
= 10/3 ft^2 per hr
