Question

one piece of pipe 21meter long is to be cut into two pieces, with the length of the pieces being in a 2:5 ratio. what are the length of the pieces​

Answer 1

Answer:

6m and 15m

Step-by-step explanation:

ratio=2:5

let the lengths of pie be 2x and 5x.

now

2x+5x= 21

7x. =21

x. =21/7=3

hence the length of pieces are:-

2x= 2*3=6

5x= 5*3=15

Answer 2

Answer:

Large piece = 15m

Small piece = 6m

Step-by-step explanation:

=>The ratio in which a pipe cut = 2:5(given)

• Let the ratio in which the pipe be cut is X
• so

=>smaller piece = 2x

=>larger piece = 5x

=>The length of pipe = 21m(given)

• According to question

=>5x + 2x = 21 m

=>7x = 21 m

=>x = 3m

• so

=>smaller piece of pipe = 2x = 2*3m = 6m

=>larger piece of pipe = 5x = 5*3m = 15m
