Before you do the steps, change the fractions given to improper fractions:
2 2/3 = 8/3
3 1/6 = 19/6
Now, I think the first step they want you to write is:
8/3 (divided by) 19/6
When you divide two fractions, it's the same as multiplying the first fraction by the reciprocal of the second fraction. (A reciprocal is a fancy way of saying you flip the fraction)
So the next step will look like this:
8/3 x 6/19
With this setup, you can cross simplify the fractions so that they look like this:
8/1 x 2/19
When you multiply this, you get 16/19

Hence for the expression 
k = 9 is the required solution.
The concentration of the hydronium ions in the milk is 5.011×10⁻⁴ if the container of orange juice has a pH of 3.3.
<h3>What is pH value?</h3>
The pH of a solution is a measurement of the concentration of hydrogen ions in the solution, as well as its acidity or alkalinity. Normally, the pH scale ranges from 0 to 14.
We have:
A container of orange juice has a pH of 3.3.
The pH value = 3.3
![\rm pH = -log[H_3O^+]](https://tex.z-dn.net/?f=%5Crm%20pH%20%3D%20-log%5BH_3O%5E%2B%5D)
![\rm 3.3 = -log[H_3O^+]](https://tex.z-dn.net/?f=%5Crm%203.3%20%3D%20-log%5BH_3O%5E%2B%5D)
Removing log:
![\rm 10^{-3.3}=[H_3O^+]](https://tex.z-dn.net/?f=%5Crm%2010%5E%7B-3.3%7D%3D%5BH_3O%5E%2B%5D)
![\rm [H_3O^+] = 5.011\times10^{-4}](https://tex.z-dn.net/?f=%5Crm%20%5BH_3O%5E%2B%5D%20%3D%205.011%5Ctimes10%5E%7B-4%7D)
Thus, the concentration of the hydronium ions in the milk is 5.011×10⁻⁴ if the container of orange juice has a pH of 3.3.
