The blue ribbon is 3 times as long as the green ribbon.
The red ribbon is 2 times as long as the blue ribbon.
If the total length of the 3 pieces of ribbon is 600 cm, what is the length of the blue ribbon?

Answer 1

Answer:

180

Step-by-step explanation:

Let, the length of green ribbon be 'x' cm

Given,

Length of blue ribbon 3 times the length of green ribbon.

Length of blue ribbon = 3x cm

Also given,

Length of red ribbon is 2 times the length of blue ribbon.

Length of red ribbon = 2* 3x

= 6x cm

Also given,

Total length of 3 pieces of ribbon is 600 cm

Length of (blue + green + red) = 600 cm

3x + x + 6x = 600cm

10x = 600

x = 600/10

x = 60 cm

Length of blue ribbon = 3x = 3*60

= 180 cm
