Question

One piece of pipe 21 meters long is to be cut into two pieces, with the lengths of the pieces being in a 2:5 ratio. What are the lengths of the pieces?

Answer 1

____________________________________

let the lengths be 2x and 5x then,


2x +5x=21

7x=21

x=3



lengths are:

2x=> 2×3=6

5x=>5×3=15

Answer 2

Bonjour !!!❤❤❤

Length of the pipe = 21 m

Let the two pieces be 2x and 5x

The equation formed :

2x + 5x = 21

7x = 21

x = 21/7 = 3m

Length of one piece = 2 × 3 = 6 m

Length of second piece = 5 × 3 = 15 m


Hope it helps.......✌✌✌
