You can put this solution on YOUR website! What is 4 2/9 divided by 3 1/6 ?

[(9*4+2)/9] / [(6*3+1)/6]

= [38/9] / [19/6]

= (38/9) * (6/19)

= (2/3)*(2/1)

= 4/3

Question 387618: I am trying to solve this problem: Divide 17/8 divided by 4/9
Supposedly the answer is a big 15 little 3 over a big 3 little 2.
I have tried to solve it by putting 17/8 * 9/4 = 153/32
Then I went further and divided that to get 4 25/32.
I also divded 17/8 and 4/9 and got 2.125 and 0.444 and got 4.786036
Then I tried 17 / 4 = 4.25 and 8 /9 = 0.888 and then and still got 4.786036
Then 17/8 * 9/4 and got 153/32 = 4.78125
It seems like the answer has a whole number and fraction on top and a whole number and fraction on bottom.
I do not understand how the answer is big 15 little 3 over big 3 little 2. I am not sure exactly what type of math question it is. All I can figure is dividing fractions.
Thanks in advance!!!

Question 993975: suppose a cake is divided into three portions,one for you.one for your friend and one four your neighbor.if you get twice as much as your friend get twice as much as your neighbor,what portion of the cake do you get?
Answer by stanbon(69061) (Show Source):
You can put this solution on YOUR website! suppose a cake is divided into three portions,one for you.one for your friend and one for your neighbor.
if you get twice as much as your friend and your friend gets twice as much as your neighbor,what portion of the cake do you get?

Let neighbor get x
Friend gets 2x
You get 4x

Ans:: 4x/(7x) = 4/7 (portion you get)

Question 993661:
1 + 2/3 / 1  2/3 the symbol in the middle means division the answer is 5 but I dont understand how. Could someone show me step by step.
Thanks in advance!
Answer by Cromlix(3061) (Show Source):
You can put this solution on YOUR website! Hi there,
Take the top equation 1 + 2/3
This really 1/1 + 2/3
Common denominator 3
obtained by multiplying
1 and 3
Now cross multiply
3 + 2/3 = 5/3
...............
Take the bottom equation 1  2/3
This is really 1/1  2/3
Common denominator 3
obtained by multiplying
1 and 3
Now cross multiply
3  2/3 = 1/3
................
You now have 5/3 on the top
and 1/3 on the bottom
Because 1/3 is dividing
it is turned upside down
You now have
5/3 x 3/1
3's cancel out
= 5/1 or 5
Hope this helps :)

Answer by macston(4006) (Show Source):
Question 991297: the probability of getting the product a perfect (square of a natural numbers) when two dice are thrown together,is
Answer by Theo(5548) (Show Source):
You can put this solution on YOUR website! the perfect squares are:
1*1 = 1
2*2 = 4
3*3 = 9
4*4 = 16
5*5 = 25
6*6 = 36
the number of possible products when you throw 2 dice is equal to 6 * 6 = 36
they are:
1*1 = 1 ***
1*2 = 2
1*3 = 3
1*4 = 4 ***
1*5 = 5
1*6 = 6
2*1 = 2
2*2 = 4 ***
2*3 = 6
2*4 = 8
2*5 = 10
2*6 = 12
3*1 = 3
3*2 = 6
3*3 = 9 ***
3*4 = 12
3*5 = 15
3*6 = 18
4*1 = 4 ***
4*2 = 8
4*3 = 12
4*4 = 16 ***
4*5 = 20
4*6 = 24
5*1 = 5
5*2 = 10
5*3 = 15
5*4 = 20
5*5 = 25 ***
5*6 = 30
6*1 = 6
6*2 = 12
6*3 = 18
6*4 = 24
6*5 = 30
6*6 = 36 ***
out of these only 8 generate a perfect square.
the probbility of getting a perfect square is therefore 8/36 = 4/18 = 2/9.
note that there are more possible factors of two number that equal a perfect square, but the highest factor has to be less than or equal to 6 which is the maximum number possible on one 6 sided die.
for example:
16 = 1*16 or 2*8 ot 4*4 or 8*2 or 16*1
out of all these factors, only 1 is possible, which is 4*4.
the only one where all possible factors can be considered is 4.
4 is the product of 1*4 or 2*2 or 4*1.
all these factors are possible when you are throwing 2 die.

21 26 ?
How you go from 18, 3, and 6 to get 21 is:
1. Find the absolute difference between the second and third numbers 3 and 6,
which is 36 or 3
2. Add that to the first number 18, and get 21.
How you go from 21, 9, and 4 to get 26 is:
1. Find the absolute difference between the second and third numbers 9 and 4,
which is 94 or 5
2. Add that to the first number 21, and get 26.
So that's the pattern, so with the numbers 24, 3, and 8, we:
1. Find the absolute difference between the second and third numbers 3 and 8,
which is 38 or 5.
2. Add that to the first number 24, and get 29.
