<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
His proportion of baseball to basketball tickets is of 3:5. He has 21 baseball tickets, hence the amount of basketball tickets is found according to the following<em> rule of three</em>:
3/5 = 21/x
Applying cross multiplication:
3x = 105
x = 105/3
x = 35.
The difference is given by:
35 - 21 = 14.
He has 14 more basketball tickets than baseball tickets.
