I think you're missing an equals sign somewhere :-)

Hi lionsshare,

The equation that you're referring to is missing some details. It should be:

2/(1 + 2/Y) = 1 and we're asked for the value of Y.

Since the fraction equals 1, the denominator and numerator must be the SAME. Thus, the denominator must equal 2....
1 + 2/Y = 2
2/Y = 1
Y = 2

Final Answer: D

We need to simplify the equation 2/(1 + 2/y) = 1. We can start by multiplying both sides of the equation by 1 + 2/y, and we have:

2 = 1 + 2/y

1 = 2/y

y = 2

Answer: D
