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

.3% of 25% =?

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 is what % of 8/18?

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
