Answer:
9. ±1, ±2, ±3, ±6
11. ±1, ±2, ±3, ±4, ±6, ±12
Step-by-step explanation:
The possible rational roots are (plus or minus) the divisors of the constant term, divided by the divisors of the leading coefficient.
Here, the leading coefficient is 1 in each case, so the possible rational roots are plus or minus a divisor of the constant term.

9. The constant is -6. Divisors of 6 are 1, 2, 3, 6. The possible rational roots are ...
±{1, 2, 3, 6}
__
11. The constant is 12. Divisors of 12 are 1, 2, 3, 4, 6, 12. The possible rational roots are ...
±{1, 2, 3, 4, 6, 12}

No. of children in lamb, chicken, duck, and turkey category is 66, 24, 18 and 12 respectively.
<h3>What is percentage ?</h3>
Percentage is the value per hundredth.
According to the given question a survey was carried out among 120 school children looked at which type of meat they preferred. 55% said they preferred lamb,20% said they preferred chicken, 15% preferred duck and 10% turkey and we have to calculate no. of children in each category.
55% said they preferred lamb, So the no. of students i this category is
= (55/100)×120
= 66 children.
20% said they preferred chicken, So the no. of children in this category is
= (20/100)×120
= 24 children.
15% said they preferred duck, So the no. of children in this category is
= (15/100)×120
= 18 children.
10% said they preferred turkey, So the no. of children in this category is
= (10/100)×120
= 12 children.
