How do you find the multplicate inverse of a rational number?
You take its reciprocal, that is you divide 1 by the number. A rational number can be written as a fraction with integer values in both the numerator and denominator, j/k. The multiplicative inverse of a number is what you have to multiply by to get a product of 1. Putting these ideas together, the multiplicative inverse is the reciprocal, or k/j: (j/k) * (k/j) = 1.
What is the Multiplicative inverse formula of complex numbers?
So if you have a number z = a + bi. Then how to find 1 divided by z. The way to figure this is to get the denominator as a pure real number. Multiplying the numerator and the denominator by the complex conjugate {a - bi} will result in a pure real denominator.(a - bi)(a + bi) = a² + abi - abi - (bi)² = a² + b². So the multiplicative inverse is(a - bi)/(a² + b²)
How do you find the percent equivalent to the nearest whole percent?
You find the percentage equivalent and the round the result to the nearest whole number.
How do you find if a number is divisible by 4?
If the last number is divisible by 4 then the whole number is divisable by 4
Is LCM the same as LCD?
The same process is used to find both. When it's a whole number, we call it the LCM. When the whole number is a denominator, we cal it the LCD.
