Answer:
Number of students who correctly describe the process = 112 students.
Step-by-step explanation:
<em>From the information provided in the question;</em>
<em>64% correctly described the process of photosynthesis.</em>
<em>63 students didn't describe correctly the process of photosynthesis.</em>
We are to find the number of students that did correctly describe the process of photosynthesis.
First of all we need to find the total number of students.Lets represent this value to be x
percentage of students who incorrectly describe the process = (100-64)%
=36%

x= 63*100/36
x=175 students.
FIRST METHOD
Number of students who correctly describe the process = 
= 
Number of students that correctly describe the process = 112 students.
SECOND METHOD
Number of students who correctly describe the process = Total number of students- number of students who didn't correctly describe the process
Number of students who correctly describe the process = 175-63
Number of students who correctly describe the process = 112 students.

Step-by-step explanation:
Good afternoon hope it is helpful
It can't be simplified because 1/3x and -5/7 aren't like terms and therefore you cannot do addition or subtraction with them.
If you meant x as in multiplied by then here is the solution:
1/3*-5/7
(1*-5)/(3*7)
-5/21
Hope this helps :)
