She can use 12 jewels for each pair of jeans. In fact, using 12 jewels per jeans implies that she will use

When multiplying a whole number by a fraction, put the whole number as a fraction over one. 9/1 times 3/4. When multiplying fractions, you multiply straight across. 9(3)=27 and 1(4)=4. The new fraction is 27/4.
96/100 into simplest form is 24/25. I hope this helps.
