Question

the mass of the piece of metal?
No wrong answer or else I will report

Answer 1

The mass of the metal is 12.6 kg

Explanation:

Let the mass of the metal be x

From the question

5/9 of the metal is 7kg

That's

`(5)/(9) x = 7`

Multiply through by 9

We have

5x = 7 × 9

5x = 63

Divide both sides by 5

`(5x)/(5) = (63)/(5)`

We have the final answer as

x = 12.6 kg

The mass of the metal is 12.6 kg

Hope this helps you
