Suppose the two numbers are x and y.
Then, the sum of THEIR reciprocals is 1/x + 1/y = y/xy + x/xy = (y + x)/xy = 7/25

Find the sum of the reciprocals of two real numbers given that these numbers have a sum of 150 and a product of 40?
1/x + 1/y = (y+x)/xy But y + x = sum = 150, and xy = product = 40 So sum of reciprocals = 150/40 = 3.75
The sum of two numbers is 65 their product of these two is 750 what is the sum of the reciprocals of the two numbers?
(50 + 15) = 65 (50 x 15) = 750 1/50 + 1/15 = 13/150
The sum of two number is 10 and their product is 30 the sum of their reciprocals is?
Suppose the numbers are x and y. The sum of their reciprocals = 1/x + 1/y = y/xy + x/xy = (y+x)/xy = (x+y)/xy = 10/30 = 1/3
What are two numbers whose product is one called?
Reciprocals, or multiplicative inverses
If the sum of two numbers is 12 and the product is 24 What is the sum of the reciprocals?
1/x+1/y y/xy+x/xy x+y/xy=12/24 12/24=1/2 1/2 is the answer.
The sum of two numbers is 10 their product is 20 the sum of reciprocals is what?
It is 0.5
What are the two conditional statements from the following Two numbers are reciprocals if and only if their product is 1?
If two numbers are reciprocals, then their product is 1. If the product of two numbers is 1, then they are reciprocals.

How can you tell if two numbers are reciprocals?
If you multiply two reciprocals, their product must be 1.
What is the product of two numbers that are opposite reciprocals?
I have a feeling that you wrote "opposite reciprocals"where you only needed to write "reciprocals".Their product is ' 1 '.
Two numbers are if their product is -1?
Two numbers are negative reciprocals if their product is -1. The numbers 1/2 and -2 are negative reciprocals. Their product is -1. This is often seen in problems involving the slopes of two lines. The slopes of perpendicular lines are negative reciprocals. Their product is -1.
