Answer 1

[tex]\frac{\frac{5}{2}+\frac{7}{18}}{0.29}-0\cdot \left(7\right) \\ \\ \frac{\frac{5}{2}+\frac{7}{18}}{0.29} \\ \\ =\frac{\frac{26}{9}}{0.29} \\ \\ =\frac{26}{9\cdot \:0.29} \\ \\ =\frac{26}{2.61} \\ \\ =\frac{26}{2.61}-\frac{7}{9} \\ \\ =\frac{26\cdot \:9}{23.49}-\frac{7\cdot \:2.61}{23.49} \\ \\ =\frac{215.73}{23.49} \\ \\ =9.18391\dots [/tex]
