The length of the rope that is left is 2 1/10 meters
Given:
The length of the rope is 6 1/2 meters
Length of the rope that is cut off = 4 2/5
To find:
Find the length of the rope that is left
Solution:
Given that length of the rope = 6 1/2
Length of the rope that is cut off = 4 2/5
Convert the given mixed fraction into an improper fraction
=> 6 1/2 = 13/2 [ 6 × 2 + 1 = 13 ]
=> 4 2/5 = 22/5 [ 4 × 5 + 2 = 22 ]
=> Length of the rope = 13/2
=> Length of the rope that is cut off = 22/5
Length of the remaining rope = 13/2 - 22/5
=> [ 65 - 44 ]/10 [ take LCM of 2 and 5 ]
=> [ 21/10 ]
=> 2 1/10
Therefore,
The length of the rope that is left is 2 1/10 meters
