teacher sorry i dont understand the blue left portion. Can explain pls
TQ teacher
Hi Jane, this is called the Branch Method, and it can be confusing with all these lines everywhere and multiplication of fractions. Maybe a model would help. I’ll get home soon and produce a drawing.

The Good Samaritan answer is actually really clear. I’m not sure if my format would make it easier for you to understand.
Maybe you can share which part you are unclear with for the Blue (Left).

TQ teacher for your explanations
No problem. I hope it’s clearer now. Good Samaritan helped the most :)

here’s my attempt to use models. drawing 45u is really painful, so you’ll need to know how to multiply fractions (1/3 of 10/15 in my example).
