Mr. And Ms. Wakani have a number of children. If 0.625 of the family are female, find the smallest number of children that could be in the Wakani family.

Answer :

Answer:

The smallest number of children that could be in the Wakani family is 5.

Step-by-step explanation:

The number of children(both male and female) is a discrete number. That is, it is a countable number, 1,2,3,...

We solve this by trial an error.

1 children:

0.625*1 = 0.625 female. Not possible.

2 children:

0.625*2 = 1.25 female. Not possible

3 children:

0.625*3 = 1.875 female. Not possible

4 children:

0.625*4 = 2.5 female. Not possible

5 children:

0.625*5 = 3.125 female. Not possible.

6 children:

0.625*6 = 3.75 female. Not possible

7 children:

0.625*7 = 4.375 female. Not possible

8 children:

0.625*8 = 5 female. Possible

The smallest number of children that could be in the Wakani family is 5.
