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%
![\frac{36}{100}*x =63](https://tex.z-dn.net/?f=%5Cfrac%7B36%7D%7B100%7D%2Ax%20%3D63)
x= 63*100/36
x=175 students.
FIRST METHOD
Number of students who correctly describe the process = ![\frac{64}{100}*total number of students](https://tex.z-dn.net/?f=%5Cfrac%7B64%7D%7B100%7D%2Atotal%20number%20of%20students)
= ![\frac{64}{100}*175](https://tex.z-dn.net/?f=%5Cfrac%7B64%7D%7B100%7D%2A175)
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.
For this case, we must find what amount represents 75% of 96.
Making a rule of three we have:
96 -------------> 100%
x ---------------> 75%
Where the variable "x" establishes the amount that represents 75% of 96.
![x = \frac {75 * 96} {100}\\x = 72](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7B75%20%2A%2096%7D%20%7B100%7D%5C%5Cx%20%3D%2072)
Thus, 72 represents 75% of 96.
To find equivalent expressions that represent the same value as the 75% of 96, you should look for expressions that result in "72"
