3/4 ÷ 5 1/2 please explain the steps
Mademuasel [1]
The easiest way to do it is to make the numbers into decimals.  All you need to do is divide them.

To convert 3/4 into a decimal just divide 3 by 4.

3 / 4 = .75

To get 5  1/2 into a decimal just ignore the 5 for now and divide the 1 by 2.

1 / 2 = .5

Now add the 5 back on and you have 5.5

So far you have converted the equation from (3/4) / 5 1/2 to .75 / 5.5

Now just divide .75 by 5.5

.75 / 5.5 = 1.136 with the 36 repeated

Delegates from 10 countries, including Russia,
ankoles [38]

Answer: 564480 arrangements

Step-by-step explanation:

First, let's consider the French and English delegates as one party because they will sit next to each other.

So total delegates if French and English are always together comes out to be 9 instead of 10.

Now, they are to sit in a row and can have different seats so the total number of ways they can sit is= 2 x 9!= 725760 ways.

Now, when Russian and U.S delegates are not to sit next to each other so consider similarly like before consider them as one unit like French and English. Now they can also change their seats so number of way for them= 2 x 2 x 8!= 161280 ways

To find out when French and English delegates are together and Russain and U.S delegates are not together we subtract the way from the original value.

725760-161280= 564480 way.
