A 1171/3m long rope is cut into equal pieces measuring 71/3m each. How many such small pieces are these?
Answer:
From the question it is given that,
The length of the rope = 117*1/3m
= (117 × 3 + 1)/3
= 352/3m
Then length of each piece measures = 7*1/3m
= 22/3 m
So, the number of pieces of the rope = total length of the rope/ length of each piece
= (352/3)/ (22/3)
= (352/3) × (3/22)
= (16/1) × (1/1)
= 16
Hence, number of small pieces cut from the 117*1/3m long rope is 16.
