Question

What is the least common denominator of 10/3m²n 1/6mn⁴

Answer 1

I'm not entirely positive about the answer, but I think I know what it's asking.

Least common denominator of fractions and variables such as this mean "What do both numbers have in common?"

10/3 and 1/6 can be on the same page if we multiply 10/3 by 2.  This gets 20/6. 20/6 and 1/6 have a common denominator of 6, and our answer for the fraction is 1/6.

We aren't done yet.  The least common denominator of the m values is just m, and same for n.

So I believe the answer is 1/6mn.  I hope this helps, and I hope that I'm right about this.  If you have further inquiries, don't hesitate to let me know!
