Question

mr. Williams and mrs.sims drove 380 miles for a school conference. Mrs.sims drove 55% of the miles. What fraction of miles did mr.williams drive? And how

Answer 1

That answer is wrong. You multiply 380 by 55 (55%) and get 209. So you subtract 209 from 380 and get 171 and to find the decimal you divide 380 over 209 and get .55 which can be 55/100 then you simplify it to 11/20

Answer 2

So 55% is really 55/100
You take 100 - 55 to find how much Mr. Williams drove
100 - 55 = 45

So Mr. Williams drove 45/100 of the miles
Simplified is 9/20 of the miles
