The general formula
can be used as a check if needed.
You would multiply 5 by 25 (125) and then subtract 7 (118). Parentheses, exponents, multiply/divide, then add/subtract.
(8/9-3/9)*2/3=5/9*2/3=10/27
Answer: x=49
Step by step explanation: to find one of the sides just subtract 35 from 60, then you get 35/25=x/35, which is 25x=1225, the last step is to divide both sides by 25 and you get the final result of 49

solving
x = 24
total number of students = 24
Checking:
75/100 * 24 = 18
