How do you determine the multiplicative inverse of a number?
The multiplicative inverse of a number is its reciprocal, meaning the multiplicative inverse of the rational number a/b is b/a. In the specialized case for integers, the multiplicative inverse of n is 1/n. This is due to the fact that a/b * b/a = 1 and n * 1/n = 1, which is the definition of a multiplicative inverse. More succinctly, to find the multiplicative inverse you "flip" the fraction or integer around to its reciprocal. This is the number that when multiplied with the original number results in a product of 1.
How do you find the multiplicative inverse of a number mod a number?
Formally, a number n, has an inverse mod p only if p is prime. The inverse of n, mod p, is one of the numbers {0, 1, 2, ... , k-1} such that n*(p-1) = 1 mod p If p is not a prime then: if n is a factor of p then there is no such "inverse"; and if n is not a factor of p then there may be several possible "inverses".
Which expression shows the quotient of a number n and 4?
n/4
What is the numerical coefficient of 49n?
The numerical coefficient of 49n is n. It refers to the constant multiplicative factors that is attached to the mathematical expression variables.
When you find the number that when multiplied by the given number they will equal 1?
The number you are looking for is called the reciprocal (or multiplicative inverse). All that sound very complicated, but the reciprocal of a number n is simply 1/n.
