Answer 1

Answer:

Mass of 2/7 of the piece of metal is 3.6 kg.

Step-by-step explanation:

5/9 of a piece of metal has a mass 7kg (Given)

⛄ So, let us find for 1 piece,

\implies⟹ Mass of 1 of a piece of metal :

\implies⟹ 7/(5/9)

\implies⟹ 63/5 kg

Similarly,

\implies⟹ Mass of 2/7 of a piece of metal

\implies⟹ 63/5 × 2/7

\implies⟹ 18/5kg

\implies⟹ 3.6 kg

★ Therefore, mass of 2/7 of the piece of metal is 3.6 kg. ★
