The Least Common Multiple of 3 and 5 is 15, which would be the denominator to use for fractions with the denominators 3 and 5.

the least common denominator would be 15. 1/5 would be 3/15 and 2/15 would stay the same..2/15. you take the denominator and multiply it by what to get 15........????........ answer: 3. so you also would multiply the numinator by 3 then take the second one. you multiply the denominator by 1 to get 15 so you do the same with thge numerator. the common denominator is 15 but to get them to fractions with the same denominators you would do that.

There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of a pair of fractions. If those numbers are denominators, the LCD is 15.
