Question

11 pieces of rope , which are of same length , can be tied together to form a rope is 58.85 meters long . How many similar pieces are needed to make a rope that is 123.05 meters long ?

Answer 1

Answer:

9 pieces of rope is 58.55 two ropes are are similar piece 123.05

Answer 2

Step-by-step explanation:

let the length of 1 piece of rope be 'a' meters

now, there are 11 pieces of rope..

therefore, 11 × a = 58.85

a = 58.85 ÷ 11

a = 5.35

Hence, length of 1 rope = 5.35 meters

now we want the no. of pieces of rope which when tied together make 123.05 meters of rope.

let required no. pieces be 'b'.

therefore, 5.35 × b = 123.05

b = 123.05 ÷ 5.35

b = 23

hence, required no. of pieces are 23.
