When numbers are grouped in twelves, each group is referred to as a dozen.

<em>There are 5 eggs left</em>

The amount of egg she bought is:

\mathbf{Amount = 1\ dozen}

Third of a dozen for breatest, means:

\mathbf{Breatest = \frac4{12}}

Quarter for breakfast, means:

\mathbf{Breakfast = \frac1{4}}

So, the fraction of eggs left is:

\mathbf{Eggs = Amount - Breatest -Breakfast }

This gives:

\mathbf{Eggs = 1 - \frac{4}{12} - \frac{1}{4}}

Take LCM

\mathbf{Eggs = \frac{12 - 4 - 3}{12}}

\mathbf{Eggs = \frac{5}{12}\ dozen}

<em>1 dozen means 12.</em>

So, we have:

\mathbf{Eggs = \frac{5}{12} \times 12}

\mathbf{Eggs = 5}

Hence, she still has 5 eggs left
