Georgia [21]3 years ago
5 0

Answer:

Only 16 problems correct

Step-by-step explanation:

Well I thought that since 80% is  4/5 then I should do 20 divided by 5 which will get me 4 and since I'm doing 4/5 I should go all the way up to 80% of 20 which will get me 16.

I'm not making that much sense but

Hope this helps :)
