First of all, I just would like to say: 

Texting in Latex is much more clear and depending on the question, just writing down without it may be confusing or ambiguous. Be together with Latex! (*^U^)人(≧V≦*)/

Note that

The denominator can't be 0 because it would be undefined.
So, we can solve the expression inside both parentheses.

Answer:
<em>3.27*10^22</em>
Step-by-step explanation:
Given the expression 9.6x10^85/3x10^63, we are to write it on scientific notation as shown:
9.6x10^85/3x10^63
= (9.8/3) * (10^85/10^63)
= (9.8/3)  * 10^{85-63}
= (9.8/3) *10^22
= 3.27 *10^22
<em>Hence the expression in scientific notation is  3.27*10^22</em>
 
        
             
        
        
        
Answer:

Given:
Total number of students in Mrs. Verner's class = 15

Number of boys = Total number of students - Number of girls = 15 - 8 = 7
So,
Percentage of boys =  × 100 = 46.7%
