A proper fraction is a fraction less than one, with the numerator less than the denominator so 1/2 is your answer
use this formula Sn=n/2[2a+(n-1)d]
here,d=a2-a1 and n= no. Of terms

Step-by-step explanation:
Answer:
x = 0 or x = 5/2
Step-by-step explanation:
Solve for x over the real numbers:
x^2 sqrt(2 x - 5) = 0
Split into two equations:
x^2 = 0 or sqrt(2 x - 5) = 0
Take the square root of both sides:
x = 0 or sqrt(2 x - 5) = 0
Square both sides:
x = 0 or 2 x - 5 = 0
Add 5 to both sides:
x = 0 or 2 x = 5
Divide both sides by 2:
Answer: x = 0 or x = 5/2
220/400 = 55%
100%- 55% = 45%
there were 45% more girls than there were boys.
