36
LCD(9, 3) = 9
LCD(12, 9) = 36
3
it equals 48
3/4 = 9/12 so LCD is 12.
12 is the LCD for 3 and 4.
In adding dissimilar fractions first you have to find the LCD! -> LCD means Least Common Denominator. *For example 2/3 3 6 9 12 + 3/4 4 8 12 the LCD is 12 put 12 under the - divide 12 to denominator and write the answer in left of given question
lcd(22, 12, 16, 9) = 1584 22 = 2 x 11 12 = 2^2 x 3 16 = 2^4 9 = 3^2 lcd = 2^4 x 3^2 x 11 = 1584
9
what you need to do is find the LCD (Least Common Denominator) of 9 and 12. there are a few ways to do this but you can google those. LCD of 9 and 12 is 36 because 9 x 4 = 12 x 3 4/9 x 4 = 16/36 and 1/12 x 3 = 3/36 16/36 - 3/36 = 13/36
2/3 and 3/4Looks like 12 here, so use form of one to convert both fractions to LCD form.4*2/4*3 and 3*3/3*48/12 and 9/12==========
1/6 + 3/4, find LCD which is 12:2/12 + 9/12 = 11/12
