EXERCICE 2 - AFRIQUE DU NORD 2001 On considère le nombre : \[ F=\frac{3 \times 10^{2} \times 1,2 \times 10^{-5}}{15 \times 10^{2}} \] Donner l'écriture scientifique du nombre \( F \).

1. \( \frac{1}{3} \times \frac{2}{5} \)

Write each decimal as a percent. \( \begin{array}{l}\text { 10. } 3.9 \\ \text { 11. } 81\end{array} \) \( \begin{array}{ll}\text { 18. } 6.75 & \text { 14. } 2.81 \\ \text { 16. } 0.0046 & \text { 17. } 0.0069\end{array} \) Write each number as a percent.

b) \( -5: \frac{10}{3}+\frac{10}{4} \)
