#### Answer

a.) True
b.) False

#### Work Step by Step

a.) $\frac{10}{2}$ $\geq$ 5
When we simplify the $\frac{10}{2}$, we get 5 since 10 divided by 2 is 5.
True
b.) $\frac{6}{10}$ $\geq$ $\frac{5}{6}$
The Least Common Denominator of 10 and 6 = 30
$\frac{18}{30}$ $\geq$ $\frac{25}{30}$
When in terms of the same denominator, 18 is not bigger or equal to 25.
