what is in the factors of both -99 and 176?
welshfella
  • welshfella
right that's it :- 11 is the GCF
jessie13
  • jessie13
okay thanks do u know #2 and #3?
welshfella
  • welshfella
for number 2 find the factors of 56 and 70 and cancel out the common ones also remember that - / - = +

because -7 * -7 = 1
jessie13
  • jessie13
ok
welshfella
  • welshfella
now you can simplify 8/10 a bit further by dividing top and bottom by 2

- to give the fraction in lowest terms

4/5?
welshfella
  • welshfella
right
jessie13
  • jessie13
okay so its just 4/5 not -4/5
jessie13
  • jessie13
right?
welshfella
  • welshfella
yes
jessie13
  • jessie13
k do u know #3??
welshfella
  • welshfella
- because both nunerator and denominator or negative
welshfella
  • welshfella
- / - = +
welshfella
  • welshfella
No its 4/5
jessie13
  • jessie13
oh okay!

  • anonymous
Yeahh
welshfella
  • welshfella
a negative divided by a negative gives a positive
jessie13
  • jessie13
oh ya i forgot that!!

No 3 - try finding the factors of -34 and 87 and see if there are any common ones. If not then the fraction is prime.
welshfella
  • welshfella
-34 = - 2* 17 87 = 3* 29 are there any common factors?
jessie13
  • jessie13
no
welshfella
  • welshfella
If not then its reduced ti its simplest form already.
welshfella
  • welshfella
right
jessie13
  • jessie13
oh okay thanks!
