. There are 12 girls and 38 boys in the 4th Grade at an Elementary School. Of these students, 9 girls and 3
boys are left handed. What percentage of the
fourth graders at this Elementary School are left
handed? (6.5B)

Step-by-step explanation:

Okay so the overall students in the 4th grade is 50

The overall students that are left handed is 11

Okay since the overall students is 50 this shouldn't be to hard, so we are going to multiply the students so we can have it out of 100%, and we will do the same with the left handed students which is 22, meaning 22% of the 4th grade is left handed

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
