A fraction of the type
a b/c is equal to
[(c x a) + b] / c
so,
9 3/ 20 = (20x9 + 3 )/ 20 = 180/20
1 1/9 = (1x9 + 1)/ 9 = 10/9
so, times is multiply ... and you get
180/20 x 10/9 = 10

you take 11/9 and turn it into a improper fraction. So its really 10/3 times 3/20. Which is 1/2.

I would think the easiest way to do this would be to turn them into improper fractions, multiply across, and then simplify. So for an improper fraction, multiply 9*20 and add 3. Put that over 20. Then 1*9 plus 1 over 9. Then multiply across.

9 3/20 * 1 1/9
183/20 * 10/9 (make improper fractions)
1830/180 (multiply)
10 1/6 (reduce to mixed fraction)

Convert both mixed fractions to improper. To convert to improper multiply your whole number by the denominator then add the numerator to the product. The number that you get will be the new numerator keep your old denominator.
Then multiply your numerators and denominators. Reduce the fraction and you have your answer.
Hope this helps.
