1. ## terminating fractions

(A) List all of the denominators between 2 and 25 that terminate.

(B) Explore the prime factors of these denominators. What do they all have in common?

2. Hello, DINOCALC09!

(A) List all of the denominators between 2 and 25 that terminate.

Answer: 2, 4, 5, 8, 10, 16, 20, 25 . . . . Right!

(B) Explore the prime factors of these denominators.
What do they all have in common?

Did you even look at the prime factors?

$\displaystyle \begin{array}{ccc}2 &=& 2 \\ 4 &=&2^2 \\ 5 & = & 5 \\ 8 &=&2^3 \\ 10 & =& 2\cdot5 \\ 16 &=&2^4 \\ 20 &=&2^2\cdot5 \\ 25 &=&5^2 \end{array}$

Notice anything?

3. yes, i see that. but i don't know how to word what i see.

am i supposed to talk about a pattern, or am i clearly missing something

4. Those denominators have prime factors of 2 or 5 only.

They are of the form: .$\displaystyle 2^m\cdot5^n$ .for nonnegative integers $\displaystyle m\text{ and }n.$

5. ## want to know in details about friction

I am having the following doubts

1. Which number is a factor of every number ?
2. Is 8/1 a unit fraction?
3. Convert 15/7 into an improper fraction.
4. Write 4/9 in workds
5. Convert 7/2 into a mixed number
6. What is proper friction and improper friction
