Hi,

Take the each number, starting with the largest, and dividing both the numerator and the denominator. The smallest product will be your answer.

11

For example, \[\frac{-99 \div 11}{178 \div 11} = \frac{9}{16.2} \]

Answer 8

@abey

With regard to a problem like this one, where one of the alternative answers is correct,
start with the largest number and see if it divides into both the numerator and denominator of the problem fraction.

Answer 9

GCF is an abbreviation for " Greates Common Factor"

Answer 10

From Mathematica 9:

{-99, 176} // FactorInteger

{
{{-1, 1}, {3, 2}, {11, 1}},
{{2, 4}, {11, 1}}
}

11 is the only common factor. {11,1} is Mathematica talk for 11^1

Answer 11
