In order to get the answer to this question you will have to find the common factor and then divide the numerator and denominator by the common factor to get the answer.
[tex]\frac{20}{10}[/tex]
[tex]CF=10[/tex]
[tex]20\div10=2[/tex]
[tex]10\div10=1[/tex]
[tex]\frac{2}{1} =2[/tex]
[tex]= \frac{2}{1} or2[/tex]
Therefore the answer is "2."
Hope this helps.
