How do you reduce a fraction?
Try a tutorial online, for example http://www.webmath.com/redfract.html and if you have a question come back and we help you for suere
You cancel factors that are common to the numerator and the denominator.
Please view my question
@emunrradtvamg Thank you very much I don't really have anything else but if I do I know you'll help me (If your online).
Sure when I can, I try to help. That is what people are for.
Can you help me w/ this? Add the following fractions. Be sure to find the common denominator (multiple) and then simplify
Did you find a common denominator for them?
In the first equation (3/16) the only thing to do is to carry out numerical division. So you will end up with 0.1875
No he's got to add two fractions by finding a common denominator, then adding the numerators of the equivalent fractions. Not convert to decimal...
Ok sorry. Just got what you really want. Wait. I definitively know what you want.
Buggy, did you find a common denominator already?
What are the denominators for the fractions you are trying to add?
Those are the fractions (except it's 3/16). which part of the fraction is the denominator?
Ok now Im gonna teach you how to get the common denominator.
\[\frac{Numerator}{Denominator}\]
The part on bottom is the denominator.
So now, what are the two denominators you are working with?
Correct. Now, we are looking for common multiplies of those two numbers. So what are the multiples of 16?
16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, 192, 208, 224, 240, 256, 272, 288, 304,
Did you figure that out? or type it in somewhere?
Do you see any multiples of 48 in that list?
What is the smallest multiple of 48 you see there?
Ok the first thing you have to do is to divide the two numbers (16 and 48) in the denominator by 2. If they both are divisible by 2, then you save this number 2. Next, you have to devide the remaining of the last divison by two again. the new two numbers are 8 and 26. If both numbers are divisible by 2 again. You save this number (2) again. 16 48 * .---------- 8 26 * 2 This number is saved 4 13 * 2 This number is saved too * Of course the remaining numbers are not divisible by 2 nor 3, and so on. This means the the common denominator is 2*2 =4 Question? Remember this is the first step
48 is the smallest multiple that 16 and 48 have in common.
So what do I do w/ the 48?
So 16 * 3 = 48. Now we need to make both of the fractions have that denominator. Since 5/48 already has that for the denominator we don't need to change it.
So you can just write 5/48 on the next column over. But to make 3/16 have a denominator of 48, we need to multiply the bottom by 3. In order to do that and keep the ratio the same, we must also multiply the top by 3.
\[\frac{3}{48} * \frac{3}{3} = ?\]
Err. \[\frac{3}{16} * \frac{3}{3}\]
We need to change the denominator of the 3/16 so it is also using our lowest common denominator.
We can multiply any number by 1 without changing it. Since 3/3 = 1, we can multiply our fraction by 3/3 and it will still have the same value.
But now it will have 48 for a denominator.
Hold on.... Let's move on to a different question...
If you are having trouble with this still I suggest this video: http://www.khanacademy.org/video/adding-fractions-with-unlike-denominators?playlist=Developmental%20Math
He explains very well the process for doing this.
(Including mine,) You have 56 replies!
You can divide both numerator and denominator by the greatest common divisor of the two. ;-)
