8 % as a fraction is 8/100. However to put it in the lowest terms you find any common multiples of both the numerator and denomimator, which is 4. You then divide each number by 4 and get 2/25 as a final answer, which is Option 1.
To turn a percent into a decimal, you drop the percent sign and divide the number by 100, or move the decimal to the left two places. 8% therefore turns into .08 which is option C
The answer to the third question is D. You may find this website helpful...

1) "Percent" means "per-hundred". So one way to write 8% is 8/100. Reduce that fraction and you get 2/25.
2) Again, percents are "per-hundred". So 8% is "Eight hundredths", or 0.08. In general, you can express a percentage as a decimal by "sliding" the decimal point to places to the left.
3) We want to find the difference of the two salaries, and then find out what percentage this difference is of the original number. If it went from $75/week to $93/week, then the difference is 93-75=18. Finding what percentage this is of 75 is more or less the same as finding what fraction if 75 it is, so it's 18/75. Divide 18 by 75 to get the decimal for this fraction, which is 0.24. Now to express this decimal as a percent, just slide the decimal over two places to get 24%.
4) Just like before, we want to find the difference, then see what percentage this decreased amount was of the original price. Notice they say the price decreased BY $2706, not TO $2706. So we just have find out what fraction 2706 is of 8200. Just divide the two: 2706/8200 = 0.33, or 33%.

Always remember, a fraction represents part of a total. Also, look at a division sign. It is a reminder of what a fraction is, because a fraction replaces the dots with numbers.
Dividing the top by the bottom gives you a decimal. Move the decimal points two places to the right, and you have a percentage.
