anonymous · Answer

multiplying something by 100 is a percent...if its 93% that really means it is .93, so multiplying it by 100 makes it 93...does that make sense at all? lol

anonymous · Answer

unit price of milk is $\frac{g}{x}$ and the unit price of cream is $\frac{g}{y}$  
ratio of unit price of milk to unit price of cream is 
$$\frac{\frac{g}{x}}{\frac{g}{y}}=\frac{y}{x}$$
