0.46666666666666. its a repeating decimal. or you could write it as 0.47.
12x2=24
The middle is extra. All you need to answer is the $12 is half his allowence left.
Answer: 95040
Step-by-step explanation:
It is important to note that selection and arrangement are two different things in permutation and combination study. In the scenario above, we have 12 books, out of which 5 is to be arranged on a shelf. The answer prescribed by 12C5 which gives 792, only solves the selection process of choosing 5 books from a total of 12. Every 5 books picked will also have to be arranged on the shelf which is solved as n!(number of ways of arranging n different objects)
Hence, to arrange 5 books from a total of 12 books on a book shelf is
nCr * r!
12C5 * 5!
792 * 120
= 95040
You mean simplify?
You can't simplify it anymore because the numerator is an even number and the denominator odd..
But,

= 0.8
And equivalent fraction:
Multiply 2 from the numerator and denominator
