Answer:

a. 1/20, 1 out of twenty, or 5%

b. three out of ten, 3/10, 30%

c. 3/20 = 3/20 yes.

Explanation:

a. It is a fraction. out of the 20 divisions there is only one 20. so there is 1 out of twenty which as a fraction is 1/20. this is equal to 1 divided by 20 wich eqauls 0.05. You move the decimal to the right twice to get 5%.

b. 6 out of twenty, 6/20. They are both even so it can be simplified.

6 ÷ 2 = 3

20 ÷ 2 = 10

It becomes 3/10, 0.3 or 30%

c. I decided that 3, 17, 2, 15, 10, and 9 are the lower right region.

the odds are 6/20 wich we know is 3/10

I only see 20 hits, but out of the 20, 6 are in the lower right region.

the odds from this is 6/20 which we know is 3/10.

We can see that the odds are equal.
