Answer:
1 1/8
Step-by-step explanation:
3/8 * 3
3/8 * 3/1
9/8
change to a mixed number
8 goes into 9 one time with 1 left over
1 1/8
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!
