Answer:
159.
Step-by-step explanation:
Percent means per-hundred.
Each big square is split into 100 equal pieces, or <em>hundredths.</em>
So, each of the 100 small squares represents 1%.
159 hundredths are shaded.
159 hundredths = 159 per hundred = 159%
159% is represented by the shaded area.
Hope this was helpful,
Good luck.
Typically you should factor the denominators first, as it will make getting the least common multiple easier. For the first denominator, you can factor out x^2, the second denominator is a perfect square, (x^2+1) (x^2-1) and the last denominator is already simplified. It appears the denominators don't have a common factor though, so yes, you would have to multiply each of the denominators out.
