Then the first step is turning \[\large \sf -2\frac{1}{7}\] into an improper fraction.

\[\frac{ -13 }{ 7 }\]

You're pretty close but it would be \[\large \sf -\frac{15}{7}\] The fraction is added along with the whole number as a negative as well.

ok

So now that we have it as a mixed fraction, we want to "divide" it away from p. But since it us a fraction, that basically just means multiplying by the reciprocal on both sides.

so? \[\frac{ -15 }{ 7 } = \frac{ -3 }{ 1 }\times \frac{ -7 }{ 15 }\]
anonymous
  • anonymous
That setup looks good. So what do you get?
anonymous
  • anonymous
\[\frac{ 7 }{ 5 }\]

Good, that would be correct :)
