Question 491454
3/4 + 3/4 = 6/4 I do not understand how the top number can be larger than the bottom number.
---
Think of the 3/4 as a pie that has 4 equal parts.
3/4 means you have three of the 4
---
So (3/4) + (3/4) means you have 3 of the 4 pieces from
a first pie and you have 3 of the 4 pieces from a second
pie.
So you have 6 of those (1/4) pieces .
Thus (3/4) + (3/4) = 6/4
-------
The rule is, " if you have the same denominators in fractions
you are adding, you should just add the numerators and write
that number over the denominator".
So (1/8) + (5/8) = 6/8
Or (2/3) + (3/3) = 5/3
===========================

 I also do not understand how to add fractions that have different bottom numbers.
If the denominators are different you have to find a number called
the least common denominator.
---
So to add (2/3) + (1/5) you have to change (2/3) and you have to 
change (1/5) so they have the same denominator.
---;
How?
(2/3) = (2/3)(5/5) = 10/15
(1/5) = (1/5)(3/3) = 3/15
----
Now you can add because the denominators are the same:
(2/3) + (1/5) = (10/15)+(3/15) = 13/15
============================================
You can find many, many sites online that will show you
how to add, subtract, multiply, and divide fractions.
Just use Google and search for "adding fractions",
or "multiplying fractions", or any other math you wish
to learn.
