There is no answer because this is a statement, with bad grammer.
There's no last name. Who even is Martin? And please write the question in a more descriptive way for me to answer it.
1.<span>Virtutes illius erant celebrata in vulgus
2.</span><span>Multa scripsit carmina poeta clarissimus</span>
Produce means to make soemthing, but since I can't see the paragraph, I can't fully answer the question, since theres no paragraph to follow it on. Sorry...
This means that there is no number, except 1, that can be divided evenly into both the numerator and the denominator. To reduce a fraction to lowest terms, divide the numerator and denominator by their Greatest Common Factor (GCF). This is also called simplifying the fraction.
Hope this helped
