The left-handed students
12% are left handed, percent means per hundred. Change percent into per 100.
12% = [tex] \dfrac{12}{100} [/tex]
Then simplify the fraction by dividing the numerator and denominator by 4
[tex] \dfrac{12}{100} [/tex]
= [tex] \dfrac{12:4}{100:4} [/tex]
= [tex] \dfrac{3}{25} [/tex]
This is the fraction showing the proportion of the left-handed students
The right-handed students
Determine the fraction showing the proportion of the right-handed students
1 - the left-handed
= 1 - [tex] \dfrac{3}{25} [/tex]
Equalize the denominator to 25
[tex] \dfrac{25}{25} - \dfrac{3}{25} [/tex]
Simplify
[tex] \dfrac{21}{25} [/tex]
This is the proportion of the right-handed students
Are there more right-handed or left-handed students?
There are more right-handed students than the left-handed students, because 21/25 is more than 3/25
