a) [tex]\sqrt{144} - \sqrt{\frac{3}{4}} + \sqrt{\frac{16}{25}} = 12 - \frac{\sqrt{3}}{2} + \frac{4}{5} = 11\frac{1}{5} - \frac{\sqrt{3}}{2}[/tex]
b) [tex]\sqrt{\frac{169}{121}} + \sqrt{\frac{225}{144}} = \frac{13}{11} + \frac{5}{4} = \frac{52}{44} + \frac{20}{44} = \frac{72}{44}[/tex]
c) [tex]\sqrt{225} - \sqrt{625} = 15 - 25 = - 10[/tex]
