The denominator always has to be the same
Example: 1/3 plus 2/4 
we know that the LCM (least common multiple) is 12 so you do 1 times 4 and 3 times for because what you do to the bottom, you have to do to the top and for 2/4 we multiply 2 times 3 and 4 times 3 that will leave us with 4/12 plus 6/12 and then you get 10/12 then you reduce that to 5/6. I hope this helps if it doesn't go to Khan Academy its a website and its on Youtube. Good Luck!

Mary has a pink dress, a blue dress, and a yellow dress. She has a black pair of shoes and a white pair. How many dress and shoe
Yanka [14]
There are two ways to solve this. 
The first way is logically. 
Mary can 
-wear a pink dress with black shoes   -wear a pink dress with white shoes
-wear a blue dress with black shoes   -wear a blue dress with white shoes
-wear a yellow dress with black shoes   - wear a yellow dress with white shoes

Count them up, and you'll get six combinations! 

Another way is simply mathematically, which is easier in my opinion. 

3 (different colored dresses) × 2 (different colored shoes) = 6 (combos)

I just need a step by step expiation please!
aniked [119]

Answer:

first I would combine terms which would give me

-4x-7=-7-4x

then I would get the variable on each side of the equal sign

0=0

lastly I would verify the solution

infinite solutions

Step-by-step explanation:

combining combining like terms would give you negative 4x - 7 which is equal to -7 - 4x. if you were to add 7 on either side and 4 on either side you would get 0 = 0 because this is correct it's infinite solutions
