Answer:
30 Students
Step-by-step explanation:
As given
Bill is in a class of 15 boys and 35 girls.
Total number of students in the class = Number of boys + Number of girls
= 15 + 35
= 50
As given
40% of the students in the class take the bus to school.
40% is written in the decimal form.
= 0.40
Number of students take bus to school = 0.40 × Total students in class.
= 0.40 × 50
= 20
.Thus
Students not take bus to school = Total students - Number of students take bus to school
= 50 - 20
= 30
Therefore 30 students not take bus to school .
Answer:
15 students
Step-by-step explanation:
First of we have to calculate how many students there are in the class. There are 15 boys and 10 girls, whish means there are 25 people in total (15+10=25).
Since 40% takes the bus to school, 60% of the sudents do not take the bus to school. The easiest way to calculate how many students is 60% is to first divide the students with 10. 25/10 is 2.5. 2.5 students is 10% of 25 students (100% divided by 10 is 10%).
To get 60%, the number of students has to be multiplied with 6, because 10% times 6 is 60%.
2.5 (10%) times 6 is 15, so the answer is 15.
