thx :)

This one is kind of easy once you see how it works.

What you do is move all the numbers with "x" to one side and all the numbers to another side.

2x + 8 = -5x + 11

2x + 5x = 11 - 8

7x = 3 

x = 3/7

Ok so you have to divide 71.40 by 84, then you multiply the result by 100 to get a percentage.

71.40 / 84= 0.85

0.85*100= 85%

Edit: I forgot to subtract it from 100%. The answer would be 15%. :)

Not sure if I am answering your question because I am reading it as the smallest possible amount for 1/a +1/b.

The way to solve this is by picking the smallest numbers you can choose, which are -5 and 1.

It would solve as 1/-5 + 1/1= 1-1/5

The final answer would be 4/5.

Hopefully this helps.

( 1/a + 1/b)             1

_________  =       ___

      a+b                  9

        [a+b]

      ______

        [ab]                      1

___________     =    ____    

                                     9

         a+b

           1                      1

   _________    =  ______

            ab                   9

            ab=9

Two distinct numbers

9 and 1

9+1 or 1+9

Both are equal to 10

sorry if I was unclear. I'm not good at latex

Thanks!

Thanks Rom!

Correct!

Thanks, CPhill.
