a) $\sqrt{0.04} + \sqrt{0.25} + 2.31 = 0.2 + 0.5 + 2.31 = 3.01$

b) $(- \sqrt{0.09}) + (- \sqrt{169}) + 12.501 = - 0.3 - 13 + 12.501 = - 0.799$

c) $\frac{\sqrt{49}}{\sqrt{4}} + \frac{\sqrt{225}}{\sqrt{144}} - 3.5 = \frac{7}{2} + \frac{15}{12} = 4.75$

d) $(- \sqrt{0.04}) \times \sqrt{0.01} + 12.02 = - 0.02 + 12.02 = 12$

e) $| \frac{- 11}{3} | + (\frac{- 1}{2})^{2} - | 4 \frac{1}{2} + (- 3.25) | = \frac{11}{3} + \frac{1}{4} - \frac{5}{4} = \frac{8}{3}$

g) $| \sqrt{169} - \sqrt{900} | - | \frac{- 5}{4} | / (\frac{1}{3} - \frac{1}{2})^{2} = 17 - \frac{5}{4} / \frac{1}{36} = - 28$
