Word problems involving rational numbers

Five pieces of satin were cut from one bale of satin. They were 1/2 m, 9/2 m, 3/10 m, 29/10 m, and 101/20 m long. Find their total length.

Their total length is:

From a chain 11 m long, two pieces of lengths m and are cut off. What is the length of the remaining chain?

Solution:
Original length of chain = 11 m

 Sum of lengths of pieces cut off:

 Length of piece left:
