Answer:
1/7 or 14.3%
Step-by-step explanation:
30% of 750 = 225 (females who study chemistry)
60% of 2250 = 1350 (males who study chemistry)
1575 = total students studying chemistry
P (female chemistry student) = 225/1575 = 1/7 (simplified)
1/7 = 14.3%
Answer is: Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 20.2
