Answer: 
Step-by-step explanation:
Given : Joanna split three pitchers of water equally among her eight plants.
i.e. The total number of pitcher plants = 8
The number of pitcher plants split by Joanna = 3
Then , the fraction of a pitcher did each plant get is given by :-

Hence, the fraction of a pitcher did each plant get = 
Answer: 36 / 2 1/4
Step-by-step explanation:
From the question, we are informed that Jared needs to drill holes 2 1/4 inches apart in a 36 inch section of his garage. The expression that he can use to figure out the number of holes he will need to drill will be:
= 36 ÷ 2 1/4
From the expression we can then calculate the number of hours to drill. This will be:
= 36 / 2 1/4
= 36 / 9/4
= 36 × 4/9
= 16
He'll need to drill 16 holes
Please see pic, I'd solved in it.
Steps to solve:
k + 10 = 27
~Subtract 10 to both sides
k = 17
Best of Luck!
