Question

A piece of string is 8m long . 3m 5cm has been cut off from it. What length of string is left in cm?
please tell fast ​

Answer 1

Answer:

Given, Length of string = 8 m

No of pieces were cut = 3

Therefore , length of each piece = 8÷3 m = 2.66 m

Answer 2

Answer:

Let the length of middle piece = x

Then length of longest piece = 3x

Then length of shortest piece = 3x−5

Thus, x+3x+3x−5=8

⇒7x-5=8

⇒x=8+5/7

⇒x=13/7
