Question

Gianna has a coin collection. she keeps 8 of the coins im her box, which is 10% of the collection how many total coins are in her collection

Answer 1

8 coins represent 10% of her collection

To find how many coins represent 100%, we can use the next proportion:

`\frac{8\text{ coins}}{x\text{ coins}}=\frac{10\text{ \%}}{100\text{ \%}}`

Solving for x:

`\begin{gathered} 8\cdot100=10\cdot x \\ (800)/(10)=x \\ 80=x \end{gathered}`

There are 80 coins in her collection
