-0.8?
OpenStudy (anonymous):
Both of the numbers are divisible by a certain number. Find that number and divide.
OpenStudy (anonymous):
Keep it in fraction form
OpenStudy (anonymous):
what would it be in fraction form?
OpenStudy (anonymous):
\[\frac{ 8 }{ -10 } \div \frac{ 2 }{ 2 }\]

Very good
So now you have \[\frac{ -1 }{ 7 } \times \frac{ -5 }{ 1 } \times \frac{ 4 }{ -5 }\]
OpenStudy (anonymous):
ok so now what do we do?
OpenStudy (anonymous):

OpenStudy (anonymous):
So now you have \[\frac{ 20 }{ -35 }\]
What goes into both of those? Find it and divide. To simplify it.
OpenStudy (anonymous):
5
OpenStudy (anonymous):
Good now simplify \[\frac{ 20 }{ -35 } \div \frac{ 5 }{ 5 }\]
OpenStudy (anonymous):
4/-7
