2/4 + 3/6

List the multiples of each denominator until a common number is found.

Multiples of 4: 4, 8, 12
Multiples of 6: 6, 12
Now we know 12 is the least common denominator of 2/4 and 3/6.

Write each fraction with common denominator.

(Common Denominator ÷ Denominator) x Numerator = New Numerator
Evaluating the formula to the first fraction, we got:

(12 / 4) x 2 = 6

Evaluating the formula to the second fraction, we got:

(12 / 6) x 3 = 6

Rewrite the fractions,
1st Fraction : 6/12
2nd Fraction : 6/12

Add the first numerator and the second numerator together then copy the denominator, as the denominator is the same and both fractions is already similar.

6 + 6   = 12
12        12

So we got 12/12 as the answer.

Simplify the answer. If mixed number, make it a improper fraction and vice versa.

12 / 12 = 1
12 / 12 = 1

So therefore, 2/4 + 3/6 is equal to 1/1, and can be simplified as 1.

I HAVE A EASY METHOD FOR IT!!!!!!

2/4 + 3/6

Multiply the denominators
2/4 + 3/6
= Denominators
= 4 and 6
= 4 x 6
= 24 will be our denominator

Use cross product multiplication to find the numerator.
2/4 + 3/6
= 12 + 12 will be our numerator.

Finalize, then simplify.
2/4 + 3/6
= 12 + 12 / 24
= 24 / 24
= 1 / 1
or

~~ ^_^ Hope it is helpful, I always use the second method because I always forget the first. Lol. Hahaha. I love cross product multiplication.

Dissimilar fractions are fractions that have different denominators.

Example:

2/4 , 3/5, 7/8

1/3 + 3/4

(1) Find for the least common multiple (LCM) of the denominators.
LCM of 3 and 4 = 12

(2) Make another fraction by putting the LCM in the denominator and leaving the numerator blank.

⇒     ---------
12

(3) Divide the LCM by the denominator of the first and second fraction, and then multiply the answer to the numerator of the first and second fraction respectively.

1/3 + 3/4

12 ÷ 3 = 4 ⇒ 4 × 1 = 4
12 ÷ 4 = 3 ⇒ 3 × 3 = 9

The answer will be our new numerator, well of course, respectively separated by the plus or the addition sign.

4             9
-------  +   -------
12          12
