### What is the trick when adding fractions?

### All proper fractions with the denominator 3?

Proper fractions are when the numberator is less than or equal to the denominator. So, the only three fractions that can be proper with the denominator as three are: 1/3, which equals approx. 0.333333333 2/3, which equals approx. 0.666666667 3/3, which equals 1.

### How can you add three fractions together?

find a common denominator for all three and then add all of the numerators together and keep the same denominator

### What is three fourths minus three eights?

3/83/4 - 3/8 = 6/8 - 3/8 = 3/8Always find the common denominator first when adding or subtracting fractions.

### How do you find the common denominator of 3 fractions?

Pick two of the fractions and find the Least Common Multiple of those two denominators. Then take that number, and find the Least Common Multiple between that and the third denominator. This number will be the Least Common Denominator between the three fractions.If you don't care to find the Least common denominator, then just take the three denominators, and multiply them together.

### 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.

### How do you add three fractions with unlike denominators?

-- Find a common denominator. (It will be a number of which all three denominators are factors. The best choice is their least common multiple.) -- Change the fractions to their equivalents with the common denominator. -- Then add their numerators to get the numerator of their sum.

### What are three improper fractions that are equaled to the whole number 2?

Improper fractions are where the numerator is greater than the denominator. If their value is 2, the numerator is twice the denominator. Examples: 2/1, 10/5, 60/30

### What is the common denominator of 6 8 10?

Least number is 120 if the three numbers are the denominators of fractions

### What are equivalent fractions for three fourths?

Fractions that are equivalent to 3/4 are: 6/8, 9/12, 12/16, etc. To find equivalent fractions, multiply the numerator and denominator by the same number.

### What is denefintion of unlike denominator?

The denominator is the number in the lower part of the fraction example: 5/8 the 8 is the denominator When adding fractions, they have to be "like" denominators. example: 5/8 and 3/8 both fractions have 8 as a denominator When they are "unlike" denominators, you have to convert them to "like" denominators to add them. example: 5/8 + 3/4 take 3/4 and multiply both the three and four by two... this will give you a new fraction of 6/8... now you can add these fractions 5/8 + 6/8 = 11/8 If your new to math. Multiplying both the numerator and denominator by any number is perfectly fine... as long as its the same number.

### How do you add three fractions?

Providing all the denominators are the same just add together the numerators otherwise find the lowest common denominator and alter the fractions accordingly

### What is the common denominator of three fourths and one fifth?

### How do you add 3 fractions with different denomenators?

You can add three fractions with different denominators the same way you add two fractions with different denominators. The only difference is that your LCD (Lowest Common Denominator) must be the same for all three fractions1/3 + 4/5 + 9/15 all have a lowest common denominator of 153, 6, 9, 12, 155, 10, 1515Now simply convert all your fractions to the appropriate denominator.1/3 + 4/5 + 9/15 = 5/15 + 12/15 + 9/15Then add like normal5/15 + 12/15 + 9/15 = 26/15and lastly reduce or simplify if necessary26/15 = 1 11/15

### How did you get seven eighths in the question one half plus three eighths?

### What are three rules you can use to compare fractions?

Rule #1 When two fractions have the same denominator, the bigger fraction is the one with the bigger numerator. Rule # 2 When comparing fractions that have the same numerator, the bigger fraction is the one with the smaller denominator. Rule # 3 You can convert the fractions and then just put the greater than, less than or equal to sign to see what the comparison is between the fractions.
