It's a fraction of fractions. Divide a fraction by a fraction.
You multiply the numerator of the top fraction by the denominator to obtain the result for the numerator. e.g. (9 X 8) = 72 and this number will be your new numerator. Then you multiply the denominator of the top fraction by the numerator of the bottom one. e.g. (-5) X (-3) = 15 Now your answer should be: 72/15 each one can be simplified to smaller numbers. 24/5 (both divided by 3 since it's their common factor)
