How can a carton of eggs show 2 ÷ 1/6?
Today you'll discover
- how a whole can be a set of things
- why one egg is 1/6 of a carton
- how to multiply and divide with sets
Think firstTwo full cartons of eggs
Each egg is 1/6 of a full carton. How many eggs fill 2 cartons?
Decide first, then press Next. The carton is the whole; each egg is one part.
Two egg cartons of 6 cells, full of eggs, each labelled 1 carton. One egg is ringed: 1 egg is 1 of 6 equal parts, 1/6 of a carton. The eggs are numbered 1 to 12, then the sentence 2 ÷ 1/6 = 12 eggs. The last step shows 9 juice boxes and packs of 4.

The big idea
A whole can be a set: one egg is 1/6 of a carton, so 2 cartons hold 12.
Both ways with sets7 eggs: 7 × 1/6 = 7/6 = 1 1/6 cartons. 3 full packs of juice: 3 ÷ 1/4 = 12 boxes.
Key word
- set
- a group of things counted as one whole, like a carton of 6 eggs

- Use a set, like a carton, to multiply or divide by a unit fraction.
