д) √2 1/4 ⋅ 1 9/16 ⋅ 1/100

д) $$\sqrt{2\frac{1}{4} \cdot 1\frac{9}{16} \cdot \frac{1}{100}} = \sqrt{\frac{9}{4} \cdot \frac{25}{16} \cdot \frac{1}{100}} = \sqrt{\frac{9}{4}} \cdot \sqrt{\frac{25}{16}} \cdot \sqrt{\frac{1}{100}} = \frac{3}{2} \cdot \frac{5}{4} \cdot \frac{1}{10} = \frac{15}{80} = \frac{3}{16}$$
