Question

5/9 of a piece of metal has a mass of 7 kg. What is the mass of 2/7 of the piece of metal?

Answer 1

Answer:-

Let the mass of the piece of metal be x

Given,

5/9 x = 7

Solving this we get,

x = 7 * 9 / 5

x = 63/5 kg

Now, 2/7 of the metal piece will be 2/7 x

Substituting the value of x here we get,

2/7 * 63/5

= 2 * 9 / 5

= 18/5

= 3.6 kg
