how do I find the answer to this equation ? c/-5=-16

Question

How do I solve this please explain.   

C/-5=-16 

Also this one too. Iam stumped on it and forgot to write notes. X+6/5=22

 

Answer 1

c/(-5) = -16

 

Since C divided by -5 is -16, then all you have to do is

multiply both sides by -5 to find the value of c

 

Note:  For any given numbers, if  a/b = c   then  a = b*c

 

c/(-5) = -16

 

(-5)[c/(-5)] = (-16)(-5)

c = 80

 

Check:  80/(-5) = -16

            -16 = -16

            Answer is correct

*************************************

2)  x + 6/5 = 22

     Subtract 6/5 from both sides

     x + 6/5 - 6/5 = 22 - 6/5

     x = 22 - 6/5

 

     We need a common denominator for 22 and 6/5

     Multiply 22 by 5/5 which is equivalent to multiplying by 1

 

     x = 22(5/5) - 6/5

     x = 110/5 - 6/5

     x = (110-6)/5

     x = 104/5

 

If necessary the improper fraction can be turned into a mixed number

 

104/5 = 20 4/5

 

Hope this helps.  Good luck
