6) \( 19 \frac{1}{17}-8 \frac{9}{17}-3 \frac{15}{17} \)

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

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

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.

c) \( 3,23-3,23= \)
