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% = 

Then simplify the fraction by dividing the numerator and denominator by 4

= 
= 
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 - 

Equalize the denominator to 25


Simplify

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

Use pythagorean’s theorem and find the missing side lengths of the two smaller triangles and add them together
13^2 - 12^2 = 5
15^2 - 12^2 = 9
5+9 = 14
14 is the length of each side of the square
14^2 + 14^2 = 19.8
19.8 is the diagonal length of the inside if the square
