You didn't give a question for number 1.

.25*.003 = .00075

1/2 of 1/4 = 1/8. (1/8)/(8/18) = (1/8)/(4/9) = (1/8)*(9/4) = 9/32

25% is same as 0.25
[X/0.25] *100% = 0.3% is how u set this up
solve for x, then u have 0.3%/100% *0.25

0.003*0.25= 7.5*10^-4

1/2 of 1/4 = 1/8
1/8 is what % of 8/18?
is same as
1/8 is what % of 4/9?
then
[(1/8)/(4/9)]*100% = X %
900/32 = X% = 25% = answer

We’ve been on the Internet for over 20 years doing just one thing: providing career information for free or at cost. We do this because we believe that the health education process is too expensive and too competitive.

We believe that all students deserve the same access to high quality information. We believe that providing high quality career advice and information ensures that everyone, regardless of income or privilege, has a chance to achieve their dream of being a doctor.
