Just simple proportions:
12(apples)          x(apples)
--------------   =   --------------
4(oranges)        7(oranges)
12*7 = 84
84/4 = 21
There are 21 apples + 7 oranges = 28 apples and oranges!

Answer:
1. -29/156 2. 38/45 3. 29/45 4. 113/24 or about 4.7 5. 457/1,  914/2,  1371/3
Step-by-step explanation:
3/13 - 5/12 can be simplified to 36/156 - 65/156. Subtract this and you get -29/156  
4/9 + 2/5 can be simplified to 20/45 + 18/45. Add this and you get
38/45
5/8 - 2/9  can be simplified to 45/72 - 16/72. Subtract this and you get 
29/45
3 1/2 + 2 5/12 can be first made irrational to 7/2 + 29/24. This can be simplified to 84/24 + 29/24 
113/24 or about 4.7
Not sure about the 457, but to convert it, you multiply it by whatever denominator you have. For example 
1x457 = 457/1 
2x457 = 914/2
And finally 3x457 = 1371/3
 
        
             
        
        
        
Answer:
3000
Step-by-step explanation:
x = original amount of GHC 
 --> 1/6x = 500
 --> 1/6x = 500
x= 3000
 
        
             
        
        
        
Answer: 
Step-by-step explanation:
For finding the quotient of the given division,
In the long division method, we will follow the following steps.
Step 1 : Here the divisor is d-2 and dividend is 
Multiply (d-2) by  and subtract the dividend by the resultant.
  and subtract the dividend by the resultant.
We get 
Step 2: Multiply (d-2) by  and subtract the remaining dividend by the resultant.
  and subtract the remaining dividend by the resultant.
We get  
Step 3 : Multiply (d-2) by  and subtract the remaining dividend by the resultant.
  and subtract the remaining dividend by the resultant.
We get  
Since, after getting 7 it is not possible further division,
Hence, Remainder = 7,
Quotient = sum of all expression by that we multiply (d-2) =
