Adrianna has fabric that is 3/4 yard long. How many 1/8 yard long pieces will she have???
Illusion [34]

Answer:

6

Step-by-step explanation:

If x is the number of 1/8 yard long pieces, then the total length is x * 1/8.  We know that the total length is 3/4 yards.  Therefore:

x * 1/8 = 3/4

Divide:

x = (3/4) / (1/8)

To divide a fraction, multiply by its reciprocal:

x = (3/4) * (8/1)

x = 24/4

x = 6

She has 6 pieces.
