**Steve**, Saturday, December 31, 2011 at 12:17am2 2/5 = 12/5

in these word problems, "of" means "times" as in half of 10 is 1/2 * 10

So, we have

3/8 * 12/5 = 36/40

while that is mathematically correct, it is normal to reduce fractions to lowest terms, by removing common factors from numerator and denominator. So, since

36/40 = 4*9/4*10 = 4/4 * 9/10,

and 4/4 = 1,

we end up with just 9/10.
