To take the square root of a fraction, break the fraction into two separate roots then calculate the square root of the numerator and denominator separately:

\( \sqrt{\frac{9}{9}} \)
\( \frac{\sqrt{9}}{\sqrt{9}} \)
\( \frac{\sqrt{3^2}}{\sqrt{3^2}} \)

If the tiger has consumed 140 pounds of food in 10 days that's \( \frac{140}{10} \) = 14 pounds of food per day. The tiger needs to consume 196 - 140 = 56 more pounds of food to reach 196 pounds total. At 14 pounds of food per day that's \( \frac{56}{14} \) = 4 more days.

A factorial has the form n! and is the product of the integer (n) and all the positive integers below it. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.

To multiply fractions, multiply the numerators together and then multiply the denominators together:

\( \frac{2}{8} \) x \( \frac{2}{5} \) = \( \frac{2 x 2}{8 x 5} \) = \( \frac{4}{40} \) = \(\frac{1}{10}\)

You have 3 out of the total of 150 raffle tickets sold so you have a (\( \frac{3}{150} \)) x 100 = \( \frac{3 \times 100}{150} \) = \( \frac{300}{150} \) = 2% chance to win the raffle.
