Convert the following to rational numbers: (a) 0.12345, (b) 5.4321.

A)

B)  

Step-by-step explanation:

To answer this question first we define what are rational numbers.

A rational number is a number that can be expressed in the form of a fraction , where x and y are integers and y ≠ 0.

a) 0.12345

This can be written in fraction form as

Now, we simplify this fraction to lowest form. Simplified form of the above fraction is . This simplified form was obtained by dividing both numerator an denominator by 5.

b) This number can be written in fraction form as

Now, we simplify this fraction.

The simplified form of the above fraction is as the numerator and denominator have no common factor.

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 %
