Question

Two numbers are such that their sum is 16 and their product is 55. What is the sum of their reciprocals ?

Answer 1

Answer:

Step-by-step explanation:

let the two numbers be x and y

x+y=16.....(1)

xy=55.......(2)

divide (1)/(2)

x/xy+y/xy=16/55

1/y+1/x=16/55

sum of their reciprocals=16/55

Answer 2

let the two numbers be x and y =

x+y=16.....(1)

xy=55.......(2)

divide (1)/(2)

x/xy+y/xy=16/55

1/y+1/x=16/55

sum of their reciprocals=16/55
