How to add fractions with unlike denominators?

Mathematics

To add fractions with unlike denominators, you need to determine their common denominator.


Say you need to add 3/9 + 7/12.


3/9 and 7/12 have a common denominator of 36.


Here how you solve this:


3/9 = 12/36

7/12= 21/36


12/36 + 21/36 = 33/36 = 11/12

Change the fractions so they have common denominators. For example. If adding 4/8 + 2/3, a common denominator of the two could be 24. Change both fractions to have a denominator of 24. To do this:

(4/8)×(3/3)= 12/24
(2/3)×(8/8)=16/24

Now that both fractions have denominators of 24, you can simply add the numerators to get your answer. in this case, it would be 28/24

Hey Guys...I need help again... Which graph represents a proportional relationship?
sukhopar [10]

Answer:

A

Step-by-step explanation:

For a graph to be representative of a proportional relationship, it must meet the following criteria:

1) It is a straight line.

2) It passes through the origin point (0,0).

3) It is neither horizontal nor vertical*.

We can see that D is not a line. So, D is not a proportional relationship.

We can also see that B and C are vertical and horizontal, respectively. They also do not cross the origin.

The only choice that is a straight line and also crosses through the origin point is A.

So, our answer is A.

And we're done!

*Note: Vertical lines are not proportional because they are not a function.

Horizontal lines are not proportional because they has a constant of proportionality of 0, which can't be the case.
