margaret buys 54 apples. she uses 1/3 apples for muffins. She used 1/2 the apples for pies. which expression as a fraction could be used to show how many apples she has left?

6/6 - 2/6 - 3/6 = 1/6

First find a common denominator which is 6. So she uses 2/6 for muffins, 3/6 for pies, and this leaves 1/6 apples left. 18 apples for muffins, 27 for pies, and 9 left over.

To determine how many apples Margaret has left after using some for muffins and pies, we can subtract the fractions representing the portions used from the total number of apples.

First, let's find out how many apples she used for muffins. She used 1/3 of the apples, so the expression representing the number of apples used for muffins is (1/3) * 54.

Next, let's calculate how many apples she used for pies. She used 1/2 of the apples, so the expression representing the number of apples used for pies is (1/2) * 54.

To find out how many apples she has left, we need to subtract the portions used from the total number of apples. Thus, the expression representing the number of apples left is:

Total Apples - Apples Used for Muffins - Apples Used for Pies

= 54 - (1/3) * 54 - (1/2) * 54

Now, let's simplify this expression:

= 54 - (18/3) - (27/2)

= 54 - 6 - 13.5

= 54 - 6 - 13.5

= 34.5

Therefore, the expression representing the number of apples Margaret has left is 34.5, or you can also express it as a fraction by writing it as 69/2 or 34 1/2.
