Question

What is the reciprocal of $7$ ?

Answer 1

Hint: For finding the reciprocal, we should first know the reciprocal meaning. So the reciprocal of any number any supposed $n$ is ${\displaystyle \frac{1}{n}}$ . And if it is reversed then we again get the original number while doing the reciprocal. So, in this way we are going to calculate it.

Complete step-by-step answer:
Now as we know what is reciprocal, so now we will calculate the reciprocal of the given number.
We have the number give as $7$
So let us assume $n=7$ , then to make the reciprocal of this number we will get
Reciprocal of $n$ , is ${\displaystyle \frac{1}{n}}$ , Hence on substituting the values, we get
$\Rightarrow {\displaystyle \frac{1}{7}}$
Therefore, the reciprocal $7$ will be ${\displaystyle \frac{1}{7}}$ .

Additional information:
A reciprocal, or multiplicative inverse, is essentially one of a couple of numbers that, when duplicated together, equivalent $1$ . If we can lessen the number to a part, finding the complementary is just an issue of interchanging the numerator and the denominator.
So to locate the multiplicative inverse of a whole number, simply transform it into a part in which the first number is the denominator and the numerator is $1$
Decimal numbers, as well, have reciprocals. To locate the proportional of a decimal number, we just have to partition $1$ by that number.
Understanding reciprocals can disentangle numerous numerical statements when you comprehend that isolating by a number is equivalent to duplicating by the proportionality of that number.

Note: We should keep in mind that the multiplicative inverse of a number that is positive and also the rational number can never be negative. Every number has reciprocal except the one number which is $0$ . So we should also know these points about the reciprocal number.
