1. 5/6 3/8, least common denominator) 2. 1/3 2/7 least common denominator)

1.) The LCD is 24

2.) The LCD 21

Step-by-step explanation:

20/24 is equivalent to 5/6 and 9/24 is equivalent to 3/8

7/21 is equivalent to 1/3 and 6/21 is equivalent to 2/7

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
