So an easy way is to pig in a number for Alan's age to figure out the ratio. 
so let's say Alan is 9 so 9*3 would be John's age, so John is 27. 
9*2 would be Ralph's age would be 18 so now you can make a fraction or the ratio since it is John/ (to) Ralph it would be John over Ralph 
so it's 27/18 now you can reduce this fraction. so divide both numbers by 9 
the new and reduced fraction is 3/2 or 3:2 that is your ratio hope this helped you have an amazing rest of the day!!!

Step 6: Patterns can provide a clear understanding of mathematical relationships. This can be seen very clearly in the form of m
kenny6666 [7]

Two more examples of relationship patterns found in mathematics are <u>Geometric sequences</u><u> and </u><u>Fibonacci numbers</u>.

<h3>What are mathematical patterns?</h3>

Mathematical patterns are a sequence of repeated arrangements of numbers, shapes, colors, letters, etc.

Mathematical patterns are usually abstract.

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence of non-zero numbers.  The first number is the product of multiplying a previous number by a fixed, non-zero number, called the common ratio.

A Geometric sequence may look like: 2, 4, 8, 16, 32, 64, 128, ..., where the common ratio is 2.

<h3>What is a Fibonacci sequence?</h3>

A Fibonacci number starts with a zero, followed by a one, then by another one, and then by a series of steadily increasing numbers.

The rule of the Fibonacci sequence is that each number is equal to the sum of the preceding two numbers, for example, 0, 1, 1, 2, 3, 5, 8, 13.

1% = (3/9)/100
