Do you add the denominator when you add fractions?
No but the denominators must be the same and you just add the numerators. If the denominators are different and you have to find which is greater you have to find a denominator that both numbers can multiply into. For example, 5/6 and 3/12 will be our fractions. 6 times to equals 12. Since 12 is the other denominator 3/12 stays the same. Thats the only time you can change the denominator.
What are the equivalent fractions of three fourth?
6/8, 9/12, 12/16..... to find more, multiply the numerator and the denominator by the same number....
How do you do equivelent fractions?
Multiply the numerator and denominator of the fraction you have by the same number. 4/7 = 8/14 = 12/21 and so on.
How Do You Make Fractions Have The Same Denominators?
You need to find the lowest common denominator. For example- 1/6 + 2/12 = 2/12 + 2/12=4/12 you need to multiply the 6 two times to get 12 and what you do to the bottom you always do to the top so you multiply 1 by 2 and get 2!
Why is nine twelfths bigger than two thirds?
To compare the 2, they both must have the same denominator, the number on the bottom of the fraction. To get 2/3 to have a denominator of 12 you have to multiply both the numerator and denominator, top and bottom number, by 4. this leaves you with 8/12. so 9/12 is clearly bigger than 8/12 since it has a larger numerator, top number, while having the same denominator, bottom number.
How do you write equivalent fractions with the lowest common denominator?
Example: 2/3 and 3/4 The LCD of 3 and 4 is 12. Multiply the numerator and the denominator of 2/3 by 4 to make 8/12 Multiply the numerator and the denominator of 3/4 by 3 to make 9/12
How do you convert a fraction to so they have a common denominator?
I assume you already know how to find the common denominator itself. Once you find the common denominator, you have to multiply top and bottom of each fraction by the same number, in such a way that the denominator is equal to the common denominator. For example: if you want to add 1/4 and 1/6, the common denominator is 12; to convert 1/4 to twelths, since you need to multiply the bottom part by 3 to convert it to 12, it follow that you multiply the top part by 3 as well - therefore, 1/4 = 3/12. Similarly, 1/6 = 2/12 (since you have to multiply the bottom by 2, you also multiply the top by 2).

What is the answer to five sixth plus one fourth?
5/6 plus 1/4 you should find a common denominator and then figure it out 12 is the lcd (lowest common denominator) multiply the numerator and denominator by the same number so the denominator equals 12 for the first it's 2 and the second 3 10/12 3/12 add it you get 13/12 or 1 and 1/12

How do you subract fractions with unlike danominators?
You find a common denominator3/4 - 1/6 = ?common denominator would be 129/12 - 2/12 =7/12you have to multiply the top and bottom by the same number3*3 and 4*3 so 3/4 = 9/121*2 and 6*2 so 1/6 = 2/12
What is three fourth minus one third?
First, both the fractions need a common denominator. The least common multiple of 4 and 3 is 12. Now multiple each fraction by the value required to have a denominator of 12. In this case, we are going to multiply 3/4 by 3/3 and 1/3 by 4/4.Now we have 9/12 - 4/12.The final answer is 5/12, which cannot be simplified.Easy you have to convert them so they have the same denominator so in reality multiply the bottom4x3 = 12then you get both the top numbers and multiply them by what there denominator was multiplied by soit would be 9/12 and 4/129/12 minus 4/12 equals 5/12
How do you add or subtract fractions with uncommon denominators?
In order to add and subtract using non-common denominators, you must find a common denominator. The easiest way of finding one is to multiply the two denominators. But there may be a smaller number (least common denominator). Mutiply the numerator and denominator of the first number by the second denominator (effectively multiplying by 1). Then multiply the numerator and denominator of the second number by the original denominator of the first number. This will leave the denominators the same. Example : add 1/3 and 1/4 Multiply 1/3 by 4/4 to yield 4/12. Multiply 1/4 by 3/3 to yield 3/12. Add the numerators. 1/3 + 1/4 = 4/12 + 3/12 = 7/12
What equivalent fractions foe three fourths?
