1. The proportion is the direct variation of a variable with another the equation which shows the proportional relationship is n = 2p.

   What are the ratio and proportion?

   The ratio is the division of the two numbers.

   For example, a/b, where a will be the numerator and b will be the denominator.

   Proportion is the relation of a variable with another. It could be direct or inverse.

   Lets’ suppose the pints (p) are directly proportional to cups(n).

   p ∝ n

   Removing proportion.

   p = kn

   Given that,

   1.5 pints equals 3 cups

   1.5 = k(3)

   k = 1.5/3 = 1/2

   So, p = (1/2)n

   n = 2p

   Hence “The proportion is the direct variation of a variable with another the equation which shows the proportional relationship is n = 2p”.

2. For every pint there is 1/2 cups
   So it would be 1:0.5
   For every cup there is 2 pints
   That would be 2:1
