Question

Use the following image to answer questions

1.) 12a =

2.) 12b =

3.) 12c =

Answer 1

12a) 1/80=0.0125 = 1.25%

12b) 5/80=0.0625 = 6.25%

12c) 5/70=0.07142 = 7.14%

Explanation:

Answer 2

:D

Explanation:

1.) One ticket out of eighty can be represented by a fractions, 1/80. To find the percentage, you can change 80 to 100 proportionally and then the difference (multiply/divide) to the 1 to find the percentage. You can also cross multiply to find the answer ("a")

`(1)/(80) =(x)/(100)`

0.0125 is the chance of getting the ticket, and multiply by 100 to get percentage.

a = 1.25%

2.)
Same thing as #1, different equation :)

`(5)/(80) =(x)/(100)`

x = 6.25%

3.)
Same thing as #2, but now, on the bottom is not 80, but instead 70.

`(5)/(70) =(m)/(100)`

m = 7.14285714286%

m = 7.14%
