Yes. When the numerator and denominator have a GCF of 1, the fraction is in the simplest form.

To simplify, find the GCF and divide both numerator and denominator by the same:

Example: simplify 30/40

30/40 divided by 10/10 (1) = 3/4

How do you simplify fractional numbers?

Divide the numerator and the denominator by the same number to simplify a fraction. This number must be a common factor of the numerator and the denominator. For example, 50 is a common factor of the numerator and denominator of 350/400. By dividing each by 50, 350/400 can be simplified to 7/8.


How do you reduce a number?

first:you find the gcm(greatest common factor)wich is the lowest number that can go evenly into the numerator and the denominator. next:you devide both the numerator and the denominator by that gcm(greatest common factor)and walla!


How do you do fraction in its simplest form?

The numerator of a fraction is the number on top and the denominator is the number at the bottom.Search for a common factor, of the numerator and denominator. That is a whole number that goes into both of them evenly.If the only such number is 1, then you are done. If not,Divide both the numerator and denominator by that common factor to give an equivalent fraction with a new numerator and denominator.Go back to step 1.


How do you reduce fractions if one number is odd?

The parity (odd or even) of a number has no relevance in reducing fractions. What is required is to find the highest common factor between the numerator and denominator. Clearly, if the numerator and denominator are bot even then 2 is a common factor and so it must be possible to reduce the fraction. The highest common factor or even a common factor may not be so obvious when both numerator and denominator are odd.For example, 21/91 = (3*7)/(13*7) = 3/13


What is the greatest common factor of a numerator if the denominator is one?

The GCF of any number and 1 is 1.


How do you put a fraction in to simplest form?

You put a fraction in simplest form by dividing the numerator and denominator by their greatest common factor. If the either the numerator or denominator is a prime number, the fraction cannot be simplified.


Explain why dividing the numerator and denominator of a fraction by the greatest common factor is the most efficient way of simplfying the fraction?

By dividing both the numerator and denominator by the same number is like dividing by 1.


Why is it when you reduce fractions you need to find the greatest common factor?

The greatest common factor is the largest number that is evenly divisible by both numbers, so if you divide both numerator and denominator by GCF, the numerator and denominator will be the smallest integers possible, and still be an equivalent fraction.


How do you multiply a whole number by an improper fraction?

The same way as multiplying a whole number by an ordinary fraction: Multiply the numerator (top number) by the whole number and put it over the original denominator (bottom number). This can then be simplified by dividing the numerator and denominator by their highest common factor; or it can be converted into a decimal (which could be a whole number) by dividing the numerator by the denominator.


What is the form a fraction is in when the numerator and the denominator have a greatest common factor of 1?

Any number is the form when the denominador and the numerador are 1.


What is the definition of simplest form in math terms?

Simplest form is a fraction in which the numerator and denominator have no common factor except 1.Numerator is the Top Number or Variable. Denominator is the Bottom Number or Variable.Or Switched I'm not really sure.


What do numerator and denominator represent?

The numerator is the number above the line in a common fraction showing how many of the parts indicated by the denominator are taken. The denominator is the number below the line in a common fraction showing the total number of parts.
