In a class, 14 out of 20 students pack their lunches. What percent of students pack their lunches? I know the answer is 70%, but could I have a step-by-step explanation? Thank you! ^^

70%

Step-by-step explanation:

(14/20)×100%= 0,7×100%=70%

70%

Step-by-step explanation:

Given that there are a total of 20 students and only 14 of them packed their lunch, we get the percent of the students who pack their lunch by simply dividing 14 by 20 then multiply the quotient by 100 and the answer is 70%. Hope this answers your question.

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
