100-r=99.52
First, add r to both sides.
100-r+r=99.52+r
And then simplify.
100=99.52+r
Then, subtract 99.52 from both sides.
100-99.52=99.52+r-99.52
And simplify.
0.48=r
So,
r=0.48
R - Right Handed
L - Left Handed
R = 9L ( the number of right handed kids is equal to having 9*number of left handed kids)
9L + L = 30 ( since total number of people in class is 30)
10L = 30
( Divide by 10 both sides )
L = 3
so... There are 3 Left Handed kids and 27 Right Handed kids ( since R = 9L , R = 9(3) = 27)
Hope this helped!
