Answer: There are 1,400 students in the school. Checked options are bolded.
Step-by-step explanation:
<em>How many students in the school?</em>
- <em />
<em> </em>(10% of the school population is equal to 140 over unknown)
- <em />
<em> </em>(unknown equals 1,400)
<em>Check all that apply:</em>
- The total number of students is greater than 140.
- The total number of students is less than 140.
- (10)(14) = 140, so 100(14) = 1,400 students.
- 140 + 10 = 150, so 150 + 140 = 290 students.
- There are 140 + 10 = 150 students at Westside Middle School.
- The percent as a part to whole ratio is StartFraction 140 Over 100 EndFraction
- The percent as a part to whole ratio is StartFraction 10 Over 100 EndFraction
