While walking outside on a field trip 75%,or 15 of the students in the class wore jackets find the number of students in the entire class.

Well, for the first question, just multiply 67 by .71 and you'll get your answer, 47.57% 

For question 2, just divide 205 by 41, which is 5, and we know that 1/5 in decimal form is .2, and .2 is equivalent to 20% 

Question 3, we know that 75% is 3/4 of 100%, so all we have to do is divide 15 by 3 to get 5, then multiply 5 by 4 to get the total students in the class, 20. 

For question 4, just divide 24 by 40 to get .6, which we know equals 60%

Ihonestly don’t no that
