Adric has a rope 9 yards long. He cuts off 7 pieces of rope, each measuring 0.75 yard. He places the 7 pieces of rope in a basket. Then he cuts the remaining rope into shorter lengths of 0.38 yard. How many pieces of length 0.38 are cut?

Solution:

0.38x+0.75*7 = 9

x = 9.9 = 9

So there are 9 pieces of length 0.38 are cut
