Hannah has one-third of a rectangle. How many more thirds does she need to make the whole rectangle?

In this question, we’re shown a rectangle. And we’re told that Hannah has shaded one-third of it. We’re asked how many more thirds she needs to make a whole rectangle. We sketched a rectangle and shaded one-third. If we divide a shape into three equal parts, we call each part a third. So, Hannah’s rectangle needs three equal parts. Here’s one, two, three. We’ve divided Hannah’s rectangle into thirds or three equal parts.

Hannah had a third of a rectangle. She needed two more thirds to make a whole rectangle. We know that a third is one of three equal parts. We need three thirds to make one whole shape. If Hannah has one-third of a rectangle, she needs two more thirds to make a whole rectangle.
