For every left handed person, there are 4 right handed persons. If there are 30 students in the class predict the number of students who are right handed.
30/5 = 6
6 * 4 = ?
If for every left-handed person there are 4 right-handed persons, we can calculate the number of right-handed students by multiplying the number of left-handed students by 4.
Let's assume there are "x" left-handed students. So, the number of right-handed students would be 4x.
Since we know that there are 30 students in the class, we can set up the equation:
x + 4x = 30
Combining like terms:
5x = 30
Dividing both sides by 5:
x = 6
Now, to find the number of right-handed students, we substitute the value of x back into our equation:
4 * 6 = 24
Therefore, there would be 24 right-handed students in the class.
To predict the number of right-handed students in the class, we need to know the ratio of left-handed to right-handed students. According to the given information, for every left-handed person, there are 4 right-handed persons.
Let's assume the number of left-handed students in the class is 'x'. According to the ratio, the number of right-handed students would be 4 times 'x', which is 4x.
If the total number of students in the class is 30, then the sum of left-handed and right-handed students should equal 30:
x + 4x = 30
Simplifying the equation, we have:
5x = 30
Dividing both sides of the equation by 5:
x = 6
Therefore, the number of left-handed students in the class is 6, and since there are 4 right-handed students for every left-handed student, the number of right-handed students is 4 multiplied by 6, which is 24.
Hence, we predict that there are 24 right-handed students in the class.
