The first package that gets both a baseball card and a football card is 225th package.
It is required to find the first package that gets both a baseball card and a football card.
Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
We have to find the value of first package that gets both a baseball card and a football card .
The multiples of 9 and 25 and the common multiple is the solution.
9 = 9, 18, 27, 36, 45, .... 225
25 = 25, 50, 75, 100, 125, 150.... 225
Therefore , the first package that gets both a baseball card and a football card is 225th package.

Answer: 225th package
Step-by-step explanation:
look for the first number where both 25 and 9 are a factor of.
25*1 is 25 which isn't a factor of 9, so it won't be 25.
25*2 is 50, which isn't a factor of 9.
75 is not a factor of 9. (you know because you don't get a whole number when you divide 75 into 9.)
100 is not a factor of 9, nor is 125, 150, 175, or 200.
However, 225 is a factor of both 25 and 9. This makes sense because 25*9 is 225.
This means that the first package with both will be the 225th package.
