Problem Solving Maths Equations

Hi Fellow viewers,Have you ever tried solving your own question? Because today Kea had to come up with a question and turn it into a math problem. This included showing 3 strategies of how we worked it out. I only could come up with 2 because I used Division of Fractions as my equation. 

I included a recording of my working out on a whiteboard so you could see what I was trying to explain. I found it hard to explain it on the slides so my 2 recordings are there. I used this method because I wanted to challenge myself.

 Do you know how to solve division of fractions? If so where did you learn it and do you have a similar way of solving it as did I?
