(Guess) You should understand more. Or wait until 9th grade.

multiply 81 by 2 then divide that by 3

final answer : 54

You need to look at this net.

3x + 2x = x       simplify the left side 

5x  = x     subtract x from both sides

4x  = 0    divide both sides by 4

x = 0

As long as we either have a terminating decimal or a repeating decimal, we can always find a fraction

Here's a procedure for a terminating decimal :

Here's a procedure for a repeating decimal :

Note......non-repeating, non-terminating decimals are irrational......there's no fraction possible......!!!!!

it is 35/100

6p+3=5p-2   add 2 to both siides, subtract 6p from  both sides

5 = -1p    divide both sides by -1

-5 = p

For now, I will leave you with two riddles:

We __x__ on the __y__ way, and we __y__ on the __x__ way

Fill out the sentence by putting the same five-letter word in the blanks marked x, and a four-letter word in the blanks marked y.

ST ND RD TH __?

What is the next pair of letters in this sequence?

Good luck! 

You will always find me in the past.

I can be created in the present,

But the future can never taintt me.

What am I?

Well, you have a 1/6 chance of rolling a 6 on a 6-sided die. Now, I'm assuming you mean exactly "2 6'ers in 6 rolls". 

So, you have a 5/6 chance of not rolling a 6. We only want a 6 twice, and thus a non-6 4 times, so we have the following:

\(\frac{1}{6} *\frac{1}{6} *\frac{5}{6} *\frac{5}{6} *\frac{5}{6} *\frac{5}{6} = \frac{625}{46656} = 0.0134\)

Hence, there is a 0.0134% chance of rolling exactly two 6's over 6 rolls of a 6-sided die.

125! equates to approximately 1.88x10^209.

To put this number in scale, 1.4959787x10^11 m is the average distance from the Earth to the Sun. So, you could go to the sun, back and forth, 6.27x10^197 times if you had to travel 125! meters.
