Question

from a rope 11m long,two pieces of lengths 2 3/5m and 3 3/10m are cut off. what is the length of the remaining rope?

Answer 1

2 3/5 = 13/5 m           and  3 3/10 = 33/10 m

length of remaining rope = 11-13/5 - 33/10 = 51/10 m
= 5.1 m

Answer 2

Length of rope = 11m 

Length of first piece = 2 3/5 m = 13/5 m

Length of second piece = 3 3/10m = 33/10 m

length of remaining piece =

11 - 13/5 - 33/10

= (110 - 26 - 33)/10

= (110 - 59)/10

= 51/10

= 5.1 m

 Answer - Length of remaining piece is 5.1m
