Answer: 
<em>or </em>negative 
Step-by-step explanation:
Find the least common multiple of the two denominators.
The LCM is 28.
To get to 28 using 7, you multiply it by 4, so we do it to its numerator as well.
4*4 = 16.
The first fraction is now - 16/28.
Just do the same to the next fraction.
4 times 7 (we used 7 instead of 4 to get to 28) equals 28.
3*7 = 21.
The second fraction is 21/28.
Now that the two denominators are the same, let's subtract the two fractions.
(note that -16/28 is the same as - 16/28)
- 
= 
(-16) - 21 = -37
So, the answer is , but can it be simplified any more? I don't think so.
There's your answer! <em>or </em>negative

Answer:
The closet equivalent of the ratio of 'a' to 'c' is:
Step-by-step explanation:
Given
i.e.
a=0.63x
i.e.
c=3/8x
Hence,
Thus, the closet equivalent of the ratio of 'a' to 'c' is:
X divided by two is 5
So you multiply 5 and 2 to get 10. Therefore x equals 10
Answer:
Step-by-step explanation:
Solution :
If 
is the total spending generated after n transactions, then 
is the spending generated during the n-th transaction. Since the government spends D dollars, then 
= D.
Then the second person will receive D dollars and spend 
dollars. Therefore, 
. The next person will receive dollars, which means they are spending 
dollars. Therefore,
....
∴
