If two numbers are reciprocals, then their product is 1. If the product of two numbers is 1, then they are reciprocals.

If you multiply two reciprocals, their product must be 1.

1/x + 1/y = (y+x)/xy But y + x = sum = 150, and xy = product = 40 So sum of reciprocals = 150/40 = 3.75

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.

I have a feeling that you wrote "opposite reciprocals"where you only needed to write "reciprocals".Their product is ' 1 '.

The Two numbers are reciprocals of each number

(50 + 15) = 65 (50 x 15) = 750 1/50 + 1/15 = 13/150

The numbers are reciprocals of one another.

Two numbers have a product of 80 their sum is 24?

The numbers are negative reciprocals of each other.

No, the Sum of two reciprocals isn't 1. However, the PRODUCT of two reciprocals is 1. For example, if you multiply 1/2 with 2/1, you'd multiply the two numeraters, which would be 1X2=2, and the two denominators, which is 2X1=2. this would cause the answer to be 2/2, or 1.

Reciprocals, or multiplicative inverses

Any two numbers whose product is '1' are each others' reciprocals.

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

If the product of two numbers is 4.2 and their sum is 4.4. then the numbers are 3 and 1.4.

The product of any two numbers is the answer to the multiplication sum. For example, in the sum 7 x 9 = 63, the number 63 is the product.

The sum of two numbers is 20 and their product is 96. Find the numbers.
