1

What is \( \frac{3}{6} \) x \( \frac{1}{8} \)?

72% Answer Correctly
\(\frac{1}{16}\)
\(\frac{2}{9}\)
\(\frac{1}{10}\)
\(\frac{12}{25}\)

Solution

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

\( \frac{3}{6} \) x \( \frac{1}{8} \) = \( \frac{3 x 1}{6 x 8} \) = \( \frac{3}{48} \) = \(\frac{1}{16}\)


2

Convert a-2 to remove the negative exponent.

67% Answer Correctly
\( \frac{2}{a} \)
\( \frac{-2}{a} \)
\( \frac{-1}{-2a^{2}} \)
\( \frac{1}{a^2} \)

Solution

To convert a negative exponent to a positive exponent, calculate the positive exponent then take the reciprocal.


3

What is \( \frac{9}{6} \) - \( \frac{7}{14} \)?

61% Answer Correctly
1 \( \frac{7}{42} \)
1
\( \frac{2}{42} \)
2 \( \frac{9}{15} \)

Solution

To subtract these fractions, first find the lowest common multiple of their denominators. The first few multiples of 6 are [6, 12, 18, 24, 30, 36, 42, 48, 54, 60] and the first few multiples of 14 are [14, 28, 42, 56, 70, 84, 98]. The first few multiples they share are [42, 84] making 42 the smallest multiple 6 and 14 share.

Next, convert the fractions so each denominator equals the lowest common multiple:

\( \frac{9 x 7}{6 x 7} \) - \( \frac{7 x 3}{14 x 3} \)

\( \frac{63}{42} \) - \( \frac{21}{42} \)

Now, because the fractions share a common denominator, you can subtract them:

\( \frac{63 - 21}{42} \) = \( \frac{42}{42} \) = 1


4

4! = ?

84% Answer Correctly

4 x 3

5 x 4 x 3 x 2 x 1

3 x 2 x 1

4 x 3 x 2 x 1


Solution

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.


5

If there were a total of 100 raffle tickets sold and you bought 4 tickets, what's the probability that you'll win the raffle?

60% Answer Correctly
3%
4%
5%
11%

Solution

You have 4 out of the total of 100 raffle tickets sold so you have a (\( \frac{4}{100} \)) x 100 = \( \frac{4 \times 100}{100} \) = \( \frac{400}{100} \) = 4% chance to win the raffle.
