Help.....I can't remember how to add fractions?

Question

Here's the example. 3/4 + 3/4=
How do I do it and show your work. I know I sound like an idiot, but I really can't remember.

Answer 1

Add numerators, denominator (bottom #) stays the same, so
3/4 + 3/4 = 6/4 or 1.5

Answer 2

Fractions consist of two numbers. The top number is called the numerator. The bottom number is called the denominator.

numerator
__________
denominator

To add two fractions with the same denominator, add the numerators and place that sum over the common denominator.

for the answer of your question

3/4 + 3/4 = 6/4
which is also 1 2/4

Adding Fractions with Different Denominators
To Add Fractions with different denominators:

Find the Least Common Denominator (LCD) of the fractions
Rename the fractions to have the LCD
Add the numerators of the fractions
Simplify the Fraction
Example: Find the Sum of 2/9 and 3/12

Determine the Greatest Common Factor of 9 and 12 which is 3
Either multiply the denominators and divide by the GCF (9*12=108, 108/3=36)
OR - Divide one of the denominators by the GCF and multiply the answer by the other denominator (9/3=3, 3*12=36)
Rename the fractions to use the Least Common Denominator(2/9=8/36, 3/12=9/36)
The result is 8/36 + 9/36
Add the numerators and put the sum over the LCD = 17/36
Simplify the fraction if possible. In this case it is not possible

Answer 3

First convert all the fractions to the lowest common denominator (all fraction have the same bottom number) then add the numerators (top numbers). Your example 3/4+3/4 already has a lowest common demoninator (4) so try 3/4+3/8

3/4 + 3/8 = 6/8 + 3/8 = 9/8 = 1 1/8

Answer 4

Well this one is easy since the denominators are the same... just add the numerators and keep the denominator the same so it would be 6/4 or simplified, 3/2 or 1.5.

3/4 + 3/4 = 6\4 simplify 3/2 or 11/2 or 1.5

If you have different denominators you need to multiply them until you have the lowest common denominator for both. so if you are adding 1/2 and 1/3 for example, you would multiply 1\2 by 3/3 and 1/3 by 2/2 and you would then have 3\6 + 2\6... you could then add them to get 5\6

1/2 + 1/3 =

1/2(3/3) + 1/3 (2/2) =

3/6 + 2\6 = 5/6

Answer 5

3/4 + 3/4 = 6/4 = 1 2/4 = 1 1/2.

Answer 6

3/4 and 3/4 ==6/4 or 1 1/2

Answer 7

3/4 and 3/4 ==6/4 or 1 1/2

Answer 8

To add fractions, you have to find the least common denominator. For this case you already have 4 thus
3+3/4 = 6/4 then you express it to the lowest terms 1 2/4 or 1 1/2

Answer 9

Add the two top numbers so it would be 6/4. Since 4/4 is 1 that would make this be 1 2/4 which you reduce to 1 1/2

Answer 10

i think it's

3/4 +3/4= denominator is same so it would be 6/4 or 1 & 2/4 the reduced 1 1/2 remember you then have to divide 4 into 6 to get that mixed fraction...

Answer 11

if the fraction has a common denominator then just combine the two and simplify. 3/4+3/4=6/4 or 3/2
if they don't have a common denominator, then make it so you do have a common denominator by finding out the LCD. Then simplify.
ex. 2/3+4/5=10/15+12/15=22/15
