Suppose the numbers are x and y
Then the sum of their reciprocals is 1/x + 1/y = y/xy + x/xy = (y+x)/xy = 10/20 = 1/2
Number x Reciprocal = 1 Therefore Reciprocal = 1/Number
To find the third number, divide the product of the three numbers by the product of the two known numbers. First, calculate the product of the known numbers: 13 × 15 = 195. Then, divide 2730 by 195: 2730 ÷ 195 = 14. Therefore, the third number is 14.
The reciprocal is the inverse of a number, or n-1. To find a reciprocal, change the number to a fraction and invert the numerator and the denominator.

To find the reciprocal of any number, divide ' 1 ' by the number. 1 / (0.8) = 1.25
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 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
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 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.
To find the reciprocal of a number, calculate [1] [divided by] [the number].
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.
