Question

Select the equality for the following and 14 karat gold ring contains 58% gold by mass

Answer 1

100g gold ring - 58g gold.

Step-by-step explanation:

Assuming that the 100% represents the 100g of the gold ring, with a mathematical rule of three we can calculate the 58% of gold:

`\begin{gathered} 100\%-100g \\ 58\%-x=(58\%*100g)/(100\%) \\ x=58g \end{gathered}`

So, in 100g of the gold ring, there are 58g of gold.
