Part A: A division problem can be written as a fraction where the numerator is divided by the denominator. Name three possible locations of a negative sign in a fraction. Part B: Provide examples illustrating the three possible locations of a negative sign in a fraction that you provided in Pa A.

\( \int \frac { e ^ { x } d x } { \sqrt { e ^ { x } } - \sqrt { e ^ { x } + 4 } } \)

2. Bir doğru açı kaç dik açı eder? \( \begin{array}{llll}\text { A) } 1 & \text { (B) } 2 & \text { C) } 3 & \text { D) } 4\end{array} \)

Ubica las fracciones en la recta numerica y despuet ordenalas de menor a mayor \( \frac{3}{4}, 0.2,-1.25 \) y \( \frac{-5}{3} \) \( \frac{8}{3}, \frac{-13}{4},-0.1 \) y 1.1 \( \frac{-23}{7},-1.8,1.7 \) y \( \frac{21}{8} \) \( \frac{-3}{10},-1.5,-2.7 \)

9) Calcule as divisões com expoente fracionário: \( 2 / 6 \quad 5 / 2 \) A) \( M: M= \)

\( \frac{2025}{2030} \) et \( \frac{2025}{2007} \)
