[tex] \frac{3}{6} [/tex] can be simplified to [tex] \frac{1}{2} [/tex]
therefore, we can see that [tex] \frac{1}{2} [/tex] is bigger than [tex] \frac{4}{10} [/tex]
or make the denominators are the same....
so, we look for the LCM of 10 and 6. That is 60. Whatever you do to the bottom you do the top. So, [tex] \frac{3}{6} [/tex] goes to [tex] \frac{30}{60} [/tex]. [tex] \frac{4}{10} [/tex] goes to [tex] \frac{24}{60} [/tex] now we can see that the first fraction ([tex] \frac{3}{6} [/tex])is bigger.
