Question

A list of numbers is given below. ${{0.9}^{2}}\mathrm{, }\sqrt{0.81},\mathrm{ }\frac{9}{11},\mathrm{ }-0.\dot{9},\mathrm{ }\sqrt[3]{0.9},\mathrm{ }\frac{3\pi }{10}$. Write down all the rational numbers. Arrange the numbers in ascending order.

Accepted Answer

(a) $0.9^2,\ \sqrt{0.81},\ \frac9{11},\ -0.\overline9$. (b) $-0.\overline9<0.9^2<\frac9{11}<\sqrt{0.81}<\frac{3\pi}{10}<\sqrt[3]{0.9}$.
