simple 8th grade math

Change the mixed fraction to improper fractions, rule a b/c=(ac+b)/c

(9/2)/(5/4)   rule (a/b)/(c/d)=(a/b)*(d/c) so

(9/2)(4/5)=36/10  now change back to mixed fraction...

rule (b/a=b/a remainder/a)

3 6/10  don't forget to reduce 6/10 by greatest common factor

3 3/5

a=3, b=3, c=5

The other problem is exactly the same...now you know the rules :D
