This is (45!) / [(45-3)! * 3! ] = 45*47*46 / (3*2) = 16,215.

Answer: 16,215 different 3 person teams

Which expression is equivalent to the following complex fraction? 1+1/y /1-1/y
Mrac [35]

<u>Answer:</u>

<u>\frac{y+1}{y-1}</u>

<u>Step-by-step explanation:</u>

To solve a complex fraction like \frac{(1+\frac{1}{y} )}{(1-\frac{1}{y} )}, take LCM of both the terms separately first to get:

1+\frac{1}{y} = \frac{y+1}{y}

and

1-\frac{1}{y} = \frac{y-1}{y}

Now combine and divide these terms to get:

\frac{\frac{y+1}{y} }{\frac{y-1}{y} }

The term y in both the denominators will be cancelled out by each other and you will be left with:

\frac{y+1}{y-1}

Therefore, the expression \frac{y+1}{y-1} is equivalent to the given complex fraction.
