Find the LCD of 3/a,3/b,1/5?
Answers:
I'll answer this only because I remember when those stupid math problems aggravated me. Also, you should put this in the math section. The way you do this is to find a common denominator by multiplying all of the denominators you have. Since you have A, B, and 5, your least common denominator would be 5ab. That would make the fractions (15b/5ab), (15a/5ab), and (ab/5ab). Also, when you get bigger numbers, do the prime factorization of the numbers and then take the lowest degree of number that is different.
