3/2

To find what fraction the selling price is of the purchase price, we have to divide the selling price by the purchase price.
The selling price is $105,000 and the purchase price is $70,000.
Therefore, we have:
[tex]\begin{gathered} \frac{105000}{70000} \\ =\text{ }\frac{3}{2} \end{gathered}[/tex]The selling price is 3/2 of the purchase price.
