We bought two pieces of fabric of the same width for the club to sew the same curtains on the windows.

We bought two pieces of fabric of the same width for the club to sew the same curtains on the windows. in the first piece 27m of fabric, and in the second 36m. 3 more curtains were sewn from the second piece than from the first. How many curtains were sewn from each piece?

Since the same curtains were sewn from both pieces of fabric, 3 more curtains were sewn from the second piece because there was more fabric in it than in the first piece. That is, the difference in the length of the fabric in each piece is due to the difference in the number of curtains sewn.

1) Find out how much more m of fabric was in the second piece than in the first: 36 – 27 = 9 (m);

2) Determine how many m of fabric was used to sew one curtain: 9: 3 = 3 (m);

3) Find the number of curtains that were sewn from the first piece: 27: 3 = 9 (w.);

4) Find out how many curtains were sewn from the second piece: 36: 3 = 12 or 9 + 3 = 12 (w.).

Answer: 9 curtains were sewn from the first piece, and 12 curtains from the second.
