\[\frac{ -8 }{ 0 }=undefined\]

Since you can't divide by 0, the fraction becomes undefined. THerefore, the statement is false automatically because of that .

It's like... For example 8/0 we can't divide by 0, so the fraction is undefined. but.. we can have a 0 on the numerator Ex 0/8 = 0 because 0 divided by 8... we're dividing nothing by 8 so the result is 0. For the first and third questions, the explanation is decent because on the first a negative divided by a negative will result in a positive due to the signs canceling out. for the third and negative divided by a positive will still be negative

Always remember\[(+)\times(+)=+\]\[(-)\times(-)=+\]\[(-)\times(+)=-\]\[(+)\times(-)=-\]

Simple rule is if there is a number on top and a zero on the bottom it is undefined (number/ zero) n/0 i use this to remind me no because n/0 is no
Johan14th
  • Johan14th
If its zero 0/number it is okay 0/n can be seen as on or okay which would equal to 0

Sorry if that was confusing
