I am, honestly, slightly confused by the question wording, so here is what I think you need! :D
We can start by listing multiplies for each:
3:
3, 6, 9, 12, 15, 18, etc
4:
4, 8, 12, 16, 20, 24, etct
We can see that the least common denominator will be 12.
Answer:
[tex]\frac{1}{3}=\frac{x}{12}=\frac{4}{12}[/tex]
[tex]\frac{1}{4} =\frac{x}{12} =\frac{3}{12}[/tex]
If you need to multiply them:
[tex]\frac{4}{12} *\frac{3}{12} = \frac{12}{144} = \frac{1}{12}[/tex]
But you do not need to use a least common denominator for multiplying and can go straight to this:
[tex]\frac{1}{3} *\frac{1}{4} =\frac{1}{12}[/tex]
Hope this helps, have a nice day!
