For example:
2/3 + 4/5 + 2 1/6 the LCM of 3, 5, and 6 (or the common denominator) is 30, so:
= 2x10/3x10 + 4x6/5x6 + 2 1x5/6x5
= 20/30 + 24/30 + 2 5/30
= 2 (20 + 24 + 5)/30
= 2 49/30
= 2 + (30 + 19)/30
= 2 + 30/30 + 19/30
= 2 + 1 + 19/30
= 3 + 19/30
= 3 19/30

Why the result of addition of two mixed number is not always a mixed number?
The fractions could add up to a whole number.
How do you find the sum of two mixed numbers?
To find the sum of two mixed numbers, turn the mixed numbers into improper fractions (multiply the base with the denominator and add the numerator), then add the two fractions. To add the two fractions, find the LCD (lowest common denominator) and add the two numerators, but leave the denominators the same.
How would you add two mixed numbers that contain unlike fractions?
you would convert the mixed numbers into fractions where the top number is greater than the bottom number, then multiply both the numerator and the denominator by a number that makes the denominators the same.
How do you add two negative mixed numbers and one positive mixed number?
Convert them to improper fractions with common denominators and proceed with the adding and subtracting.
Rename two thirds and three fourths as fractions with 12 of the denominator then add the Renamed fractions write the sum as a mixed number?
Two thirds and three fourths can be renamed as fractions with 12 of the denominator as 8/12 and 9/12 respectively. The sum of the renamed fractions as a mixed number is 1 5/12.
Can the sum of two mixed numbers be equel to 2 Explain why or why not?
No. Each mixed number is made of a whole number and a fraction. When you add them, you have the sum of two whole numbers and two fractions. Since each whole number must be at least ' 1 ', the sum of two whole numbers must be at least ' 2 ', and the two fractions will always make it more than ' 2 '.
When asked to find the sum of two mixed numbers with different denominators you should before you add?
Convert the fractions into equivalent fractions with the same denominator. In actually adding mixed numbers, it is easier to convert the mixed numbers into improper (top heavy) fractions, do the addition, simplify the resulting fraction and convert any resulting improper fraction back into a mixed number.
How do you add two fractions with a different denominator?
You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.
How do you multiply a mixed fraction by a whole number?
You would turn the mixed number into a fraction by multiplying the whole number(the one in the mixed fraction) by the denominator and then you add the numerator to the product. You would then put that number you get and out it over the denominator. For the other whole number, you would put it over one and multiply the two fractions!
Can you get a mixed number from diving two proper fractions?
I dun think so:)
How do you do improper fractions?
Well let's say that you have the mixed number one and a half. The one counts as 2 two's. Then you add the two two's with the other two that made up the half and get three over two.
Do you need to get the LCM of mixed numbers?
Only to add, subtract, or compare two fractions. Note: Technically, to add two fractions (for example) you don't need the LEAST common multiple; any common multiple will do. As an example, if you want to add 1/4 + 1/6 (or any mixed number that ends with this fraction), you can use 24 as a common denominator (you can obtain this by multiplying 4 x 6), even though the least common multiple is 12.To add two mixed fractions, the easiest way is usually to add the whole part and the fractional part separately.
