1/x + 1/y y/xy + x/xy (y+x)/xy= 10/20 10/20=1/2 1/2 is the answer.
Two numbers with a product of 1 are called reciprocals. If you have a number and want to find the reciprocal of it, simply divide 1 by the number. For example, the reciprocal of 5 is 1/5, and the reciprocal of 700 is 1/700.
Reciprocal is the multiplictive inverse. For example, 1/x when multiplied by x gives 1. x is the reciprocal of 1/x. Thus, if a number, when multiplied by a given number, produces 1 as the product, then that number is called the reciprocal of the given number.
The reciprocal of a number plus the reciprocal of twice the number equals Find the number. 1/2 find the number
The reciprocal of one number is another number which when both are multiplied, give a product of 1. In the case of a whole number, the reciprocal is 1 divided by that number.... so the reciprocal of 25 is 1/25 or 0.04
A reciprocal is the number you must multiply another number by to get the product of 1. The reciprocal of 4 (which is the same as 4/1) is 1/4. The reciprocal of 3/8 is 8/3. The reciprocal of 13 is 1/13.This can also be expressed using exponents. The reciprocal of any value x is equal to x-1. So the reciprocal of a/b is (a/b)-1, which is equal to b/a.To find a reciprocal, put the number under one. If it is a fraction, flip the fraction. Whatever the reciprocal is, remember that it must always multiply to one with the original number.

the reciprocal of a number is 1 divided by the number. if you want to find the reciprocal of a fraction you would need to swap the fraction numbers around and then multiply by 1. and then divide the answer.It is 1 divided by the number.
The reciprocal of a number plus the reciprocal of twice the number equals Find the number. 1/2 find the number
You make it an improper fraction and switch the bottom and top numbers
The reciprocal of one number is another number which when both are multiplied, give a product of 1. In the case of a whole number, the reciprocal is 1 divided by that number.... so the reciprocal of 25 is 1/25 or 0.04
Number x Reciprocal = 1 Therefore Reciprocal = 1/Number

"The sum of a number and three times another number is 18. find the numbers if their product is a maximum?"
The reciprocal of a number is what the original number is multiplied by to get 1. To find this you can simply divide 1 by the number you want the reciprocal for or, if the number is in fraction form, switch the denominator and numerator.
Multiplying by dividing can refer to finding the product of two numbers by dividing one number by the reciprocal of the other. For example, to find 5 multiplied by 3, you can divide 5 by 1/3 (which is the reciprocal of 3). This results in 5 x 3 = 15.
To find the reciprocal of a number, calculate [1] [divided by] [the number].
