Since Angie has 12 3/4 yards of fabric and all and each costume requires 7/8 yards, you can divide 12 3/4 by 7/8.
12 3/4 ÷ 7/8
= 51/4 ÷ 7/8
= 51/4 • 8/7 (remember that dividing by a fraction is the same thing as multiplying by it’s reciprocal)
= 51/1 • 2/7 (after simplifying)
= 102/7
= 14 4/7
Angie can make 14 costumes. She cannot make the 15th one because she’ll run short of fabric.

Answer:
1 2/21
Step-by-step explanation:
We start out with:
3/7 + 2/3
In order to add them together, they must have an equal denominator. An easy way to find an equal denominator is the cross method. We divide 7 by 3 and 3 by 7, giving us a denominator of 21:
3/21 + 2/21
But what about the numerators? You do the same thing as before (multiplying by the other's denominator). Now we have:
9/21 + 14/21
We add both together (the denominator stays the same) and we get 23. 23/21 is correct but not in simplest form. We remove 21 from the numerator (because it is a whole) and finally get:
1 2/21!
