does anybody know about the lcd math method {lowest common denominator.?

Answer 1

To find the LCD, for instance, between 5, 10 and 14, just do the following:

1. Divide all the numbers by the smallest number you can (usually 2), even if not all the numbers can be divided by it.
2.Divide again the result by the same number if you can, if you can´t, divide them by the next smallest number you can use.
3. Do this until you get 1 as a result in all the numbers (It doesn´t need to be at the same time)
4. Multiply all the numbers by which you divided and you will get youl lcd:) For instance:

5 10 14 | /2
5 5 7 | /5
1 1 7 | /7
1

Since 2*5*7=70, the lcd for 5, 10 and 14 is 70 :)

Answer 2

It's useful in adding and subtracting fractions. For example, to add 1/3 and 1/4 you must find the smallest number which both 3 and 4 divide into a whole number of times, which in this case is 12. Multiply 1/3 by 4/4 (=1 so it does't change the value) and you get 4/12. Multiply 1/4 by 3/3 (also =1) and you get 3/12. Add them together for the answer of 7/12.

If the problem is something like 1/6 + 1/4, multiplying the denominators would give you 24. This would work but 24 is not the *lowest* common denominator. 1/6 + 1/4 = 4/24 + 6/24 = 10/24, which can be simplified to 5/12.

Answer 3

The liquid crystal reveal is the backside non-0 quantity that is a distinctive of the two denominators. a million/6 and 2/3 are comparable in that 3 might nicely be made into 6, as 3X2 is 6. hence, the liquid crystal reveal is 6. Now, for the subsequent step: multiply the two the numerator and denominator of two/3 with the help of two, so as that the two fractions have a denominator of 6. you're able to get 4/6. Now the fractions are equivalent, as they may well be truthfully in comparison. I desire you the suitable of all, and desire i become of a few help.

Answer 4

like find the LCP of the denominator?

Answer 5

I do.
