To simplify a radical, factor out the perfect squares:

\( \sqrt{48} \)
\( \sqrt{16 \times 3} \)
\( \sqrt{4^2 \times 3} \)
4\( \sqrt{3} \)

To add these radicals together their radicands must be the same:

2\( \sqrt{112} \) + 8\( \sqrt{7} \)
2\( \sqrt{16 \times 7} \) + 8\( \sqrt{7} \)
2\( \sqrt{4^2 \times 7} \) + 8\( \sqrt{7} \)
(2)(4)\( \sqrt{7} \) + 8\( \sqrt{7} \)
8\( \sqrt{7} \) + 8\( \sqrt{7} \)

Now that the radicands are identical, you can add them together:

An integer is any whole number, including zero. An integer can be either positive or negative. Examples include -77, -1, 0, 55, 119.

To divide fractions, invert the second fraction and then multiply:

\( \frac{2}{6} \) ÷ \( \frac{3}{7} \) = \( \frac{2}{6} \) x \( \frac{7}{3} \)

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

\( \frac{2}{6} \) x \( \frac{7}{3} \) = \( \frac{2 x 7}{6 x 3} \) = \( \frac{14}{18} \) = \(\frac{7}{9}\)

You have 7 out of the total of 150 raffle tickets sold so you have a (\( \frac{7}{150} \)) x 100 = \( \frac{7 \times 100}{150} \) = \( \frac{700}{150} \) = 5% chance to win the raffle.
