Answer:

Fractions can be compared both by finding the common numerators and denominators.

Step-by-step explanation:

The fractions can be compared by finding the common denominators, as an example consider the fractions

[tex]\frac{2}{3}[/tex] and [tex]\frac{5}{6}[/tex]

To compare the two fractions we must find their common denominator, which is the least number divisible by both 3 and 6. The common denominator is 6.

Thus

[tex]\frac{2}{3}=\frac{2*2}{3*2}=\boxed{\frac{4}{6}.}[/tex]

Now comparing this to [tex]\frac{5}{6}[/tex]  we see that

[tex]\frac{5}{6}>\frac{4}{6}[/tex]

Therefore

[tex]\frac{5}{6}>\frac{2}{3}[/tex]

Thus fractions can be compared by finding the common denominators.

The fractions can be compared by finding the common numerators. As an example consider the fractions

[tex]\frac{7}{2}[/tex] and [tex]\frac{7}{5}[/tex]

These fractions share the same numerators but different denominators. The denominator of 7/2 is less than that of 7/5, therefore we conclude that

[tex]\frac{7}{2}>\frac{7}{5}[/tex]

This is how fractions are compared by finding the common denominators.
