The ratio of the amounts is x/24.
The amount invested in company A is unknown. The amount is represented by the variable "x". The amount invested in company B is $24. We need to find out the ratio of the amount invested in company A to that of company B. We need the answer as a fraction.
Let the ratio be represented by the variable "r". A ratio compares two numbers. A ratio expresses how much of one thing there is in comparison to another. A fraction is a portion of a whole or, more broadly, any number of equal pieces. In ordinary English, a fraction denotes the number of components of a specific size.
r = x/24
Hence, the ratio of the amount invested in company A to that of company B is x/24.

To calculate unit rate, you are simply finding the unit ($) per rate (pound). Start by setting up a ratio, in this case, you have $7.96 per 5 pounds. You want to find the price per pound. Fractions are just another way to write a division problem, so divide.
$7.96/5 = approx. $1.59 per pound
