Question

Compare the models for 1/3 and 2/6 how dose the number of parts relate to the sizes of the parts

Answer 1

There is no model attached, but, we can imagine a model.
Take a whole pizza.
There’s six slices and you have three friends.
You want it to be even and so each friend gets two slices.
But, originally, the pizza could’ve been sliced into three bigger pieces anyways.
1/3 = 2/6
