Answer 2

3/4 piece of metal has mass of 15kg

⇒ 3/4 piece = 15 kg

Find the mass of 1 piece of the metal:

3/4 piece = 15 kg

1 piece = 15 ÷ 3/4

1 piece = 15 x 4/3

1 piece = 20 kg

Find the mass of 2/5 piece of the metal:

1 piece = 20 kg

2/5 piece = 2/5 x 20

2/5 piece = 8 kg

Answer: 2/5 piece has a mass of 8 kg
