Question

Three strings of lengths 50m75cm, 68m 58cm and 121 m 3cm, respectively, are joined
together to get a single string of greatest length, find the length of the single string obtained. If
this single string is then divided into 12 equal pieces, find the length of each piece.​

Answer 1

Answer:

240.36 m and 20.03 m

Step-by-step explanation:

Length of string 1 = 50m 75 cm = 50.75 m

Length of string 2= 68m 58 cm = 68.58 m

Length of string 3= 121m 3 cm = 121.03 m

Total length of greatest string = l₁ + l₂ + l₃ = 50.75 + 68.58 + 121.03 = 240.36 m

Now, the string is divided into 12 piece

∴ Length of each new string = Total length / 12 = 240.36 / 12 = 20.03 m
