Question

one piece of pipe 21 meters long is to be cut into two pieces with one piece being 40 percent of total length what are the lengths of the pieces?​

Answer 1

Answer:

Length of smaller piece = 8.4m

Length of bigger piece = 12.6m

Step-by-step explanation:

Let us consider the two pieces to be P₁ and P₂

We know that :-

Total length = 21m

Length of piece P₁ = 40% of total length

⇒ 40 / 100 × 21

⇒ 2 / 5 × 21

⇒ 8.4m

Length of piece P₂ = (Total length) - (Length of piece P₁)

⇒ 21 - 8.4

⇒ 12.6m

Hope this answer helps you.

Answer 2

Total pipe’s length = 21 metres

Percentage in which the pipe is to be cut down= 40% and 60%

40% of total pipe length= 40/100* 21 = 42/5= 8.4 metres

60% of total pipe length= 60/100*21= 63/5= 12.6 metres
