Answer:
[tex]\sf{-3\displaystyle\frac{1}{2} }[/tex]
Solution:
- First, we need to flop the second fraction over.
- Then, we need to multiply the first fraction times the second fraction.
- In order to multiply fractions, we need to multiply the numerator of the first fraction times the numerator of the second fraction:
- [tex]\displaystyle\frac{1}{2} *-\frac{7}{1}[/tex]
- [tex]-\displaystyle\frac{7}{2}[/tex]
- Now, let's convert the improper fraction into a mixed number.
- First, how many times does 2 go into 7? (evenly)
- The answer is 3.
- Now, multiply 3 times 2. We get 6.
- Subtract 7-6. We get 1.
- The denominator stays the same.
- Therefore, the answer is
- [tex]-3\displaystyle\frac{1}{2}[/tex]

Step-by-step explanation:
[tex] = \frac{1}{2} \div ( - \frac { 1}{7}) \\ [/tex]
Move the ( - ) sign forward
[tex] = - \frac{1}{2} \div \frac{1}{7} \\ [/tex]
[tex] = - \frac{1}{2} \times \frac{7}{1} \\ [/tex]
[tex] = - \frac{7}{2} \\ [/tex]
