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.
How do you multiplicative an inverse when its a whole number?
The multiplicative inverse of any non-zero integer, N is 1/N.

What does mutplicative inverse?
The multiplicative inverse of a number "n", is another number, which you can write as "1/n", defined such that the number, times its multiplicative inverse, is equal to 1.
What is the multiplicative inverse of a whole number?
Let m be a whole number, then the multiplicative inverse of m is a number n such that mn=1 since 1 is the multiplicative identity. There is only one choice for n, it is 1/m since m(1/m)=1
What is the multiplicative inverse of ½?
The multiplicative inverse of an element x (in a set S) is an element, y, of the set such that x*y = y*x = 1 where 1 is the multiplicative identity. y is denoted by x^(-1). For the set of numbers, the inverse of x is 1/x.
How do you find the multiplicative inverse of a number mod a number?

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".
A multiplicative inverse of 5 module 7 is?
A multiplicative inverse of 5 mod7 would be a number n ( not a unique one) such that 5n=1Let's look at the possible numbers5x1=5mode 75x2=10=3 mod 75x3=15=1 mod 7 THAT WILL DO IT3 is the multiplicative inverse of 5 mod 7.What about the others? 5x4=20, that is -1 mod 7 or 65x5=25 which is 4 mod 75x6=30 which is -5 or 2 mod 7How did we know it existed? Because 7 is a prime. For every prime number p and positive integer n, there exists a finite field with pn elements. This is an important theorem in abstract algebra. Since it is a field, it must have a multiplicative inverse. So the numbers mod 7 make up a field and hence have a multiplicative inverse.

What is the definition of opposite numbers?
The additive opposite of a positive is a negative, and the opposite of a negative is a positive. If you reverse the sign twice (opposite of opposite) you have the original number. The same applies to an inverse (multiplicative opposite): the inverse of any inverse for a nonzero number is the original number. n (1/n)(n) = n
What expression shows 8 less than 3 divided by a number n?
