There are 36 students in a class. 1/3 of the students go to school by bus. 1/4 of the students walk to school, the rest are taken to school by their parents. How many students are taken to school by their parents?
36 * 1/3 = 36/3 = 12
36 * 1/4 = 36/4 = 9
36 - 12 - 9 = ?
by bus ---> (1/3) of 36 = 12
walkers ---> (1/4) of 36 = 9
how many are left over ??
To find out how many students are taken to school by their parents, we need to subtract the number of students who go to school by bus and those who walk from the total number of students in the class.
Step 1: Find the number of students who go to school by bus.
1/3 of the students go to school by bus, so we can calculate this by multiplying the total number of students by 1/3:
Number of students who go by bus = (1/3) * 36 = 12
Step 2: Find the number of students who walk to school.
1/4 of the students walk to school, so we multiply the total number of students by 1/4:
Number of students who walk = (1/4) * 36 = 9
Step 3: Calculate the number of students taken to school by their parents.
We subtract the number of students who go by bus and those who walk from the total number of students in the class:
Number of students taken by parents = Total number of students - Number of students who go by bus - Number of students who walk
Number of students taken by parents = 36 - 12 - 9 = 15
Therefore, there are 15 students who are taken to school by their parents.
