Express the repeating decimal number as a quotient of two integers. \( 4 . \overline{45} \) \( 4 . \overline{45}=\square \) (Simplify your answer. Type an improper fraction.)

Q1. Write a number in the box to make this correct \[ \frac{3}{5}<\frac{\square}{100}<0.7 \]

Exencice 1 - POLynesie 2001 Calculer le nombre B en détaillant les calculs. \[ B=\frac{10^{7} \times 10^{-3}}{10} \] On donnera le résultat sous la forme \( 10^{n} \).

\( \begin{array}{ll}\text { a) } 3 \sqrt{12}-5 \sqrt{27}+\sqrt{243}-\frac{1}{5} \sqrt{75} & \text { b) } \sqrt{14+\sqrt{7-\sqrt[4]{81}}}\end{array} \)

A. \( \frac{3}{5}+\frac{7}{11}=\frac{\square}{55} \)
