You can figure out if two fractions are bigger by just cross multiplying the numerator and denominator of each fraction.
\(\frac{5}{12} \frac{3}{7}\)
Multiply the 5 and 7, and then the 3 and 12. Be sure to start with the numerator of the first fraction.
\(\frac{5}{12} \frac{3}{7}\)
5 7 = 35, 3 12 = 36
So \(\frac{3}{7}\) is bigger.
