# When is a denominator used?

A denominator is the bottom number in a fraction. It is also the same thing as the divisor in a division problem. For example: in the fraction 1/2, 2 is the denominator; the mathematical expression of the fraction 1/2 is the same as the mathematical expression of 1 divided by 2. It can also be expressed in ratio form (i.e. 1:2).

Either: when given a fraction with a surd as the denominator, rationalising the denominator; Or, when given a fraction with a complex denominator, to make the denominator real.

### What is the conjugate of a denominator?

This is related to the technique used to eliminate square roots from the denominator. If, for example, the denominator is 4 + root(3), you multiply both numerator and denominator by 4 - root(3). In this case, "4 - root(3)" is said to be the "conjugate" of "4 + root(3)". When doing this, there will be no more square roots in the denominator - but of course, you'll instead have a square root in the numerator.

### Denominator of 127?

If that's 127, the denominator is 1. If that's 1/27, the denominator is 27.

### Is the denominator at the top or bottom?

### What do you divide first numerator or denominator?

you switch the numerator with the denominator then multiply the numerator first then the denominator.

### What are the parts of a fraction?

The numerator, which is the number above the line. The denominator, which is the number below the line. The denominator defines the size of the fractional parts of a whole, and the numerator tells how many there are. A fraction is often used to express the division of the numerator by the denominator.

### What is a denominator in a mathematical equation?

A denominator is a common part of a mathematical equation. The denominator is found below the line of a fraction. In 1/4, the number 4 is the denominator.

### What is a rule for ordering fractions with the same denominator?

If they have the same denominator, then (assuming the denominator is positive), igbore the denominator for determining the order. That is, order the numbers by their numerators. In the unlikely event that the denominator is negative, the above method will give the reverse order.

### What is the importance of the conjugate in rationalizing the denominator of a rational expression that has a radical expression in the denominator?

To eliminate the radical in the denominator.

### What is rationalize a denominator?

process by which a fraction containing radicals in the denominator is rewritten to have only rational numbers in the denominator.

### What 2 operations are used with lowest common denominator?

The least common denominator or (LCD) of two or more fractions is the least common multiple of the denominators.

### How are equivalent fractions used when subtracting unlike fractions?

First you find a common multiple of the denominators. The least common denominator is handy but not essential. This number will be the denominator of the answer - before simplification. For both fractions find an equivalent fraction whose denominator is this common denominator. Carry out the subtraction on the new numerators to give the numerator of the answer. Simplify the result for the final, simplified answer. First you find a common multiple of the denominators… Read More

### How do you rationalize a denominator?

You multiply both, the numerator and the denominator, of the fraction by the complex conjugate of the denominator. The complex conjugate of (x + iy) is (x - iy). Thus (u + iv)/(x + iy) =[(u + iv)*(x - iy)]/[(x + iy)*(x - iy)] and the denominator is then x2 -ixy + ixy - i2y2 = x2 + y2 which is real but it may or may not be rational. If this denominator is irrational… Read More

### What is the greatest common denominator of 66 and 93?

There is no greatest common denominator, for whatever figure someone comes up with for the greatest common denominator, I can always add the lowest common denominator of 66 and 93 (which is 2046) and get an even higher common denominator.

### What does it mean to rationalize a denominator?

Sometimes the denominator is an irrational or complex number (depending on the level that you are at). Rationalising the denominator requires to multiply both the numerator and denominator of the fraction by a suitable number - usually the conjugate - so that when simplified, the denominator is rational - normally an integer.

### How do you rationalize the denominator of a radical expression that has two terms in the denominator?

You multiply the numerator and the denominator by the "conjugate" of the denominator. For example, if the denominator is root(2) + root(3), you multiply top and bottom by root(2) - root(3). This will eliminate the roots in the denonimator.

### How do you rationalizing the denominator?

Generally, the process involves multiplying the numerator and denominator of the fraction by the same number. This number is selected so that the original denominator becomes rational. In the process the numerator may become rational. If the original denominator is of the form âˆšb then you multiply the numerator and denominator by âˆšb/âˆšb. If the original denominator is of the form a+âˆšb then you multiply the numerator and denominator by (a-âˆšb)/(a-âˆšb). NOTE change of sign… Read More
