Well young girl here's a hint.

You know for sure that 50% of any value is always its half right? As in 50/50 chances.

So 60% would be slightly more than the half of 80 (50% would be 40) so I say 48.

In a more arithmetical language you could say that 60% = 60/100 so 60% of 80 is the same as 60*80 then /100 = 48.

Question 2 I suppose you're looking for 30.5% of 70. Then same this as above. 50% = 35 (half) so my quess is 30.5% is not too far below 35 hummmmm 21.35.

Now let's see: 30.5% = 30.5/100 (you can get rid of the decimal by saying 305/1000 of 70 so 305*70 then divided by 1000 = 21.35

Third is the same but asked differently of course.

1200 * x = 24 where x is a percentage in the form of 0.decimal.

1200 * x = 24 so x = 24/1200 = 0.02 so you can say 2%
Proof: 1200 * 2 then /100 = 24

Remember that 0.05 is 5% and 0.18 is 18% and 1.39 is 139%

D.

a) 48 from 80 times 0.6

b) Question is unclear. Do you mean 30.5 percent of 70? That would be 21.35
30.5 of 70 would otherwise probably mean 30.5 times 70 which isnt a listed answer

c) 2.0% from 24 divided by 1200 is 0.02=2%

You know, you could go through each answer to determine which one is correct, INSTEAD of cheating. These are skills you need to learn, instead of trying to get by, shame on those who even responded. Not trying to be mean...
