Nancy's mom said a project would take 1/2 yard of fabric. Nancy had 1/4 yard of white and 1/4 yard of pink. If she added these together, would Nancy have enough yardage for the project? true or false ?

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
