Mrs. Andrew's classroom has 4 rows of desks with 3 desks in each row. She placed 2 pencils on each desk. How many pencils did Mrs. Andrew place on the desks altogether?

b) \( \left(-\frac{5}{12}\right) \cdot \frac{24}{15}-\left(-\frac{13}{6}\right)+\left(\frac{2}{9}\right)^{-2}= \)

Use the order of operations to simplify this expression \( \left(\frac{2}{5}+\frac{1}{10}\right) \cdot \frac{1}{2} \)

4. Rewrite one of the factors as the sum of two terms in each expression and use the Distributive Property to verify each product. \( \begin{array}{ll}\text { (a) } 4 \times 17=68 & \text { (b) } 9 \times 34=306\end{array} \)

Evaluate: \( \frac{2}{5}-\frac{1}{3}+\frac{2}{5} \)

Exit Ticket Determine the answer to the following problem using a mod and using mathematical calculations. It takes \( 2 \frac{2}{3} \) cans of paint to paint a hallway. The painters have painted \( \frac{4}{5} \) of the hallway. How much paint have they used? (Thinking) (Application) (Communication)
