Question

The students at Maryville High School were challenged to join the Great American Smokeout. One-fifth of the students signed a pledge saying they would not smoke on November 20. A third of the students promised to talk to someone who smoked about the dangers of smoking. The rest of the students didn't participate. There are one thousand, sixty-six students at MHS. How many of the students didn't participate in the Great American Smokeout?​

Answer 1

To find the number of students who didn't participate, subtract the number of students who did participate from the total number of students at Maryville High School. One-fifth of the students signed a pledge and a third of the students promised to talk to someone who smoked.

Step-by-step explanation:

To find the number of students who didn't participate in the Great American Smokeout, we need to subtract the number of students who did participate from the total number of students at Maryville High School.

One-fifth of the students signed a pledge, which is equal to 1/5 * 1066 = 213 students.

A third of the students promised to talk to someone who smoked, which is equal to 1/3 * 1066 = 355.33 students. Since we can't have a fractional number of students, we round down to 355 students.

To find the number of students who didn't participate, we subtract the students who signed a pledge and the students who promised to talk to someone from the total number of students: 1066 - 213 - 355 = 498 students.
