A ratio stays equivalent when you multiply or divide the same thing to both numbers, just like fractions:

First of all, you can simplify it to

3:4 by dividing both numbers by 5.

Now you can multiply both numbers by 5 to get 75:100

Finally, you can multiply both numbers by 3 to get the ratio 45:60

You can find an equivalent ratio by either simplifying or multiplying your values. To simplify this example, just divide the numerator and denominator by the GCF which is 5
15/5 = 3, 20/5 = 4
So a ratio that is equivalent to 15:20 is 3:4

The number of books is given as:

n = 4

Take the factorial of both sides

n! = 4!

Evaluate

n! = 4 * 3 * 2 * 1

n! = 24

Hence, there are 24 different possible arrangements she can make
