Question 1
Consider this: j starts at 5 (when k=0) and 7 is added every time k increases by 1. If k increases by 2, j will increase by 14.

Question 2
If 1/6 is really 0.16, then if we use inverse operations and multiply 0.16 by 6, it should equal 1, right? However, 0.16 times 6 is only 0.96!
4/5 is not equal to 0.08 because 0.08 times 5 is only 0.4,
1/3 is not equal to 0.3 because 0.3 times 3 is only 0.9.
1/4 is equal to 0.25, because 0.25 times 4 is 1.

Question 3
What percent of 250 is 75?
Well, a percent is basically just a fraction out of 100.
Take a look at these equivalent fractions.
[tex]\frac{75}{250}=\frac{15}{50}=\frac{30}{100}=\boxed{30\%}[/tex]
