Answer:
Step-by-step explanation:
11. I can't see the full problem statement, so I'm unable to answer the question.
12. Answer below:
"one half" = [tex]\frac{1}{2}[/tex]
"negative five eighths" = [tex]\frac{-5}{8}[/tex]
To evaluate the expression, you multiply the two numbers together:
[tex]\frac{1}{2} * \frac{-5}{8} = \frac{1 * -5}{2 * 8} = \frac{-5}{16}[/tex]
13. Answer below:
"one third" = [tex]\frac{1}{3}[/tex]
"eleven sixteenths" = [tex]\frac{11}{16}[/tex]
To evaluate the expression, you multiply the two numbers together
[tex]\frac{1}{3} * \frac{11}{16} = \frac{1 * 11}{3 * 16} = \frac{11}{48}[/tex]
