√20/8 + √45/9 please solve this question

Dear student, \frac{\sqrt{20}}{8} + \frac{\sqrt{45}}{9} = \frac{\sqrt{4 \times 5}}{8} + \frac{\sqrt{9 \times 5}}{9} = \frac{2 \sqrt{5}}{8} + \frac{3 \sqrt{5}}{9} = \frac{\sqrt{5}}{4} + \frac{\sqrt{5}}{3} = \sqrt{5} (\frac{1}{4} + \frac{1}{3}) = \sqrt{5} (\frac{3 + 4}{12}) = \frac{7 \sqrt{5}}{12} Regards
