Question 27 The cost of 750 feet of cable was \( \$ 90 \). At this rate, how much would 350 feet cost?

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

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

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

\( \begin{array}{ll}\text { 10) }-3 \frac{2}{5} \times-\frac{6}{5} & \\ \begin{array}{ll}\text { A) } 4 \frac{2}{25} & \text { B) } 2 \frac{139}{175}\end{array}\end{array} \)

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