10. In a game of tug of war, your team changes \( -1 \frac{3}{10} \) feet in position every 10 seconds. What is your change in position after 30 seconds?

Write each as a decimal. U 27) \( 6 \frac{5}{8} \)

If you need to review, return to lesson 4. Marilyn takes 6 hours to exercise and train the horses. It takes Junesh \( 25 \% \) longer than Marilyn to do the same job. They decide to work together. How long does it take them to do the job when they work together? Answer: Together they do the job in

\( \begin{array}{ll}\text { 1) } \frac{3}{2}-3 \frac{1}{8} & \\ \begin{array}{ll}\text { A) }-1 \frac{17}{40} & \text { B) } \frac{39}{40} \\ \text { C) }-1 \frac{3}{56} & \text { D) }-1 \frac{5}{8}\end{array} \$ \begin{array}{ll}\end{array} \text { l }\end{array} \)

Add and simplify. 15) \( \frac{7}{4}+\frac{7}{12} \)

3) \( \frac{3}{2}+\left(-2 \frac{5}{8}\right) \)
