Melissa has three different positive integers. She adds their reciprocals together and gets a sum of $1$. What is the product of
Whitepunk [10]

If the three integers are a,b,c, then we have

\dfrac1a+\dfrac1b+\dfrac1c=1

We can combine the fractions on the left side:

\dfrac{bc}{abc}+\dfrac{ac}{abc}+\dfrac{ab}{abc}=\dfrac{bc+ac+ab}{abc}=1

\implies abc=bc+ac+ab

Answer:

The answer is A. You just have to plug in.

Step-by-step explanation:

10 + 3 = 13

13 = 13 (true)

5(3) - -6/3= 13

15+ 2 = 13
