# how to simplify odd number fractions

First find a common factor(a number the will go in another number w/out fractions...e.g 3 is a factor of 9 and 21) for both numerator and denominator and see how many times it "will go in" both number. Other examples of fractions that can be further reduced include 3/12, … Repeat the process by another number until you … Remember that there are other definitions related to fractions … 2 ÷ 2 = 1 6 ÷ 2 = 3 We check our fraction to see if we can simplify the fraction further. So, we will divide both the numerator and the denominator by 2. If you change 5/20 into 5/(2*2*5), suddenly the problem is a piece of cake--cancel the five from the top and bottom of the fraction and you get 1/(2*2) which equals 1/4. This calculator will also simplify improper fractions … The rules of divisibility will simplify this process: Start with 2: EVEN numbers (ones that end with 2, 4, 6, 8, or 0) can be divided by two without a remainder (ie. Here both numerator and denominator are even numbers, so we can use 2 to divide the fraction. 2 and 6 are both even numbers, so they are both in the two times table and can be halved. To perform math operations on fractions before you simplify them try our Fractions Calculator. Likewise we can't divide exactly by 3 (10/3 = 3 1 3 and also 35/3=11 2 3). It sounds more complicated, but the easiest way to simplify fractions is to break them into the smallest parts possible--prime numbers. We will talk about two ways to simplify fractions. It is the same way you simplify even fractions. This time the denominator is an odd number, so you know it isn’t divisible by 2. No need to check 4 (we checked 2 already, and 4 is just 2×2).. A "fraction" is a whole number over any other whole number except zero. Method 1. The result is 6/27. The largest number that divides into both 2 and 6 is 2. The easiest way is to try dividing both the numerator (top number) and the denominator (bottom number) by each prime number. Example: Simplify the fraction 10 35:. Simplifying fractions mean that we want to reduce a fraction to its simplest form as possible. This is because both 2 and 4 can be divided by 2 to equal the fraction ½. 161 divided by 2 is 80 and … You can see from the picture below that these fractions are the same, but ½ is the simpler of the two fractions and is fully reduced. The result is 2/9. Try the next highest prime number, which is 3: 6 ÷ 3 = 2, and 27 ÷ 3 = 9. Simplifying Fractions by: Karin Nicole, 161/2 is an improper fraction. The numerator and denominator are both still even numbers, so divide by 2 again: 12 ÷ 2 = 6 and 54 ÷ 2 = 27. You could also write this improper fraction as a mixed number. If your improper fraction numbers are large you can use the Long Division with Remainders Calculator to find whole number and remainder values when simplifying fractions by hand. An example of a fraction that isn't fully reduced is 2/4. Hi Kenneth. So, 4/8 -> 4/2 (numerator divided by 2) and 8/2 (denominator divided by 2) -> 2/4. Example 1: Simplify the fraction 4/8. exp:19/12. This also means 161 divided by 2. If you divide, you will have an answer of 80.5. You get a decimal because 161 is an odd number, therefore, it is not divisible by 2. We can divide this fraction by 2 again. But 5 does work! We can simplify fractions by dividing both the numerator and the denominator by a common number without remainders. The new fraction we have is 2/4. they are divisible by 2). Dividing by 2 doesn't work because 35 can't be exactly divided by 2 (35/2 = 17½). So there is an example showing that a fraction can indeed be an odd number. Suppose we have a fraction 4/8. So 6/2 is a fraction. I think you know that it equals 3, which is another whole number and an odd number.
