Re: fractiona
Hi jackielo;
Welcome to the forum! That is not false. The greater the numerator the bigger the fraction.

Re: fractiona
Hi Bob;
Yes that is true.
Hi jackielo;
the greater the numerator the greater the fraction.
That statement is false for the reason that Bob pointed out.

Re: fractiona
hi bobbym
I did
suppose
Under what circumstances does the inequality switch?
Answer: If you multiply or divide by a negative
