If you refer to your previous question,
"what is the greatest common factor <i>if</i> 1/5 of 2/15 and 4/9? "

I can understand the typo "of" was written as "if".

We do not usually find common factors of fractions. At 5th grade, you may be preoccupied with common denominators. I understand the question if it was:
"what is the least common denominator of 1/5 of 2/15 and 4/9? "
That is why drwls wanted you to copy the question correctly so that the answer (if given) is for the right question.

A common denominator for two or more fractions can ALWAYS be found. The question is finding the <i>least</i> common denominator to minimize arithmetic calculations.

Can you recheck your question and show what you can do?
