A teacher uses 2/3 of her yearly supply of construction paper during the first quarter. She then uses 5/7 of what's left during the second quarter. During the third quarter, she uses 3/4 of what she has left (from the end of the second quarter). How much construction paper does the teacher have left for the fourth quarter of the school year?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Construction paper => x
2x/3 + 5x/21 + 6x/84 = 82x/84
Construction paper left = x/42 or 1/42
