Of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed or left-handed students? Explain. Write your answers in simplest form.
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
