Out of 1,200 students, 700 are boys. Therefore, the fraction would be

.
To convert this into a percentage, divide 700 by 1,200.

= 0.583333 (or just 0.583 if you round)

Answer:
F= (9C+160)/5
Step-by-step explanation:
C=5(F-32)/9
make F the subject of the formula= isolate F
5(F-32)=9C
5F-160=9C
5F=9C+160
F= (9C+160)/5
check: a, b, c are all positive integers (a=9, b=160, c=5)
