6%

Step-by-step explanation:

90 + 60 = 1507 + 2 = 9Set up a proportion: $\frac{9}{150} = \frac{x}{100}$ Cross multiply, then divide: 9 × 100 = 900, 900 ÷ 150 = 6So, 6% of students in 6th grade were left-handed

I hope this helps!

8%

Step-by-step explanation:

Firslty, we need to see the number of people in 7th grade:

90 + 60 = 150

And we need to see how many poeple are left-handed:

9 + 3 = 12

12/150

Convert it into a decimal = 12 ÷ 150 = 0.08

0.08 = 8%

First, we write a fraction that expresses the number of sixth grades who can write left-handed out of all sixth graders. 9+3=12, 90+60=150, so the fraction is 12/150. 12 and 150 are both divisible by 6, since 1+2=3 and 1+5+0=6 and 12 and 150 are even, so we can divide 12/150 by 6/6, a form of 1, to get 2/25. Percentages are basically the numerator of a fraction with 100 as the denominator. Since 25 is a divisor of 100, we can simply multiply 2/25 by 4/4 to get 8/100. 8/100 as a percentage is 8%, which is our final answer.

If 12 out of 150 students are left handed, the percentage of students that are left handed is 8%.
To find the percentage of students that are left-handed, divide 12 by 150.
12/150 = 0.08
Next, multiply the quotient (0.08) by 100.
0.08*100 = 8

0.08 or 8%

Step-by-step explanation:

to find probability, number of left handed/total

this would be (9+3)/(90+60), which simplifies to 12/150 = 0.08.
