Question

there are three pieces of ribbon. Two of the pieces and half the third piece, laid end to end, make one metre. What is the length of a piece in centimetre​

Answer 1

Answer:

Let the length of a piece of ribbon be x

Now, according to question

(2x+2x+x)/2=1

=> 5x/2=1

=> 5x=2

=> x=2/5

length of one piece is 2/5 metre so,

2/5 × 100cm=40 cm

(1m=100cm)
