Zero! Who could possibly a Red Sox Fan when the Yankees are in town? Let them mourn the loss of the Babe forever!
Now you have a group of 20 and a group of 15. What you are being asked is what is the smallest number that you could find that can be divided evenly by 15 and 20? Is it 20 * 15=300 or is it something smaller.
The way to solve this is to write out the factors of 15 and 20.
15 = 3*5
20 = 2 * 2 * 5
So the smallest number is
one 3
two 2s
one 5 Don't count these 5s twice.
LCM = 3 * 2 * 2 * 5
LCM = 60.
The smallest group she could see of Yankee Fans and Red Sox Fans is 60 if they both must be equal.
Answer 60 Red Sox Fans.
We have been given the steps to solve the equation as
Step 1: 2x = 18
Step 2: x = 18 − 2
Step 3: x = 16
There is an error in step 2.
We have 
x is in multiplication with 2. So in order to get rid of 2 from the left hand side, we perform opposite operation of multiplication i.e. division.
So we must divide both sides by 2.
Therefore, A is the correct option.
A) She did not divide 18 by 2.
Well this is easyyy:) you just need to multiply 4 and 2/7 by 1/2
buttt before we set up our question lets get 4 and 2/7 as an improper fraction
2
4 ----
7
we do that by multipying the 4 and 7 and then adding 2 soo lets do that
4 x 7 = 28
28 + 2 = 30
look we have our numerator!! (the top number)
and we dont have to do anything to the numerator just keep it the same as 7 :) lets look at our new improper fraction
30
------
7
see now we can set up our problem:)
30 1
------ x -----
<span> 7 2
</span>now all we do is multiply across:)
30 1 = 30 x 1 = 30
------ x -----
<span> 7 2 = 7 x 2 = 14
</span>here is our new fraction
30
------
14
wait lets simplify it by dividing each number by 2
30 ÷ 2 = 15
------
<span> 14 </span>÷ 2 = 7
ahh this is better here is our simpified fraction
15
-------
7
or as a decimal it is 2.142857143
either one is the correct answer:)
