The proffesional runner can run 50/12 miles or 4 1/6.
To figure this out turn both mixed numbers into improper fractions (denominator x whole number + numerator) and multiply both of the improper fractions ( numerator x numerator denominator x denominator )
Start first by determining the number of books of each category. if x is the nbr. of nonfiction then x+40 is the nbr of fiction. x+x+40=400
so x=180 is the nbr. of nonfiction and 220 is the nbr of fiction.the probability would be 180/400×179/399 so 2nd option
