Answer:
9.193259%
Step-by-step explanation:
In order to obtain the percentage of military members in the reserves who are Black, we will have to multiply the percentage of Black military members in the reserve by the percentage of military members in the reserve. This is calculated as follows:
Military members in the reserves who are Black (%) = 77.1771% × 11.9119%
= 9.193259%
Therefore, he percentage of military members in the reserves who are Black is 9.193259%
.
Example
For example, let assume the total number of active members in the military is 100.
To obtain the number of military members who are in the reserves, we multiply 77.1771% by 100. This gives us 78 approximately.
To obtain the number of military members in the reserves who are Black, we multiply 11.9119% by 78 we got above who are active military members in the reserves. This gives us 9 members approximately.
I wish you the best.
