Find the weight of a 1m metal pipe:
3 m = 7.6 kg
1 m = 7.6 ÷ 3 = 38/15 kg
Find the weight of a 7.8 m metal pipe:
1 m = 38/15 kg
7.8 kg = 38/15 x 7.8 = 19.76 m
Answer: The 7.8 kg metal pipe will weight 19.76 kg.

Given weight of 3 m long pipe = 7.6 kg
Weight of 1 m long pipe = 7.6/3 kg
= 76/30kg
= 38/15 kg
Weight of 7.8 m long pipe =( 38/15 )× 7.8 kg
= 19.76
The required weight of the pipe = 19.76 kg
