Plug in numbers. First, let a = 2, and b = 2. In this case, the value of Quantity A is

1

2

+

1

2

= 1.
The value of Quantity B is

1

1 2 + 1 2

=

1

1

= 1
In this case, the two quantities are equal. Now, let a = 10 and b = 10. In this case, the value of Quantity A is

1

10

+110 =

10

=

1

5

. The value of Quantity B is

1

1 10 + 1 10

=

1

2 10

= 5.
In this case, Quantity B is greater. A relationship cannot be determined.
