Answer:
<h2><em><u>D. 4/25</u></em></h2>
Step-by-step explanation:
As,
0.16
= 16/100
= <em>4/25.</em> [Taking common factor 4 from both 16 and 100]
You should be able to multiply 91 by 8 to get the sum of the first 8 tests, then add the score on the 9th test. Then to get the average of the sum of the 9 tests you need to divide it by 9.
((91*8)+78)/9=89.555555555555.... So, 90%
