Question

0.4 part of a 9.3 g ornamental chain is made of gold. If the chain is cut into 6 equal pieces. how much gold is there in each piece?

Answer 1

$0.4\left(\frac{4}{10}\right)$ part of the ornamental chain is made up of gold.

Let the whole chain = x

A weight of the whole chain = 9.3g

Amount of gold in the whole chain $=\frac{4x}{10}$

A weight of gold in the whole chain

$=\frac{4\times 9.3}{10}$

= 3.72g

Each piece have gold $=\frac{3.72}{6}$

=0.62g
