What is \( \frac{4}{6} \) x \( \frac{1}{5} \)?
| \(\frac{2}{5}\) | |
| \(\frac{2}{15}\) | |
| \(\frac{2}{3}\) | |
| \(\frac{2}{9}\) |
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{4}{6} \) x \( \frac{1}{5} \) = \( \frac{4 x 1}{6 x 5} \) = \( \frac{4}{30} \) = \(\frac{2}{15}\)

The least common multiple (LCM) is the smallest positive integer that is a multiple of two or more integers.
This property states taht the order of addition or multiplication does not mater. For example, 2 + 5 and 5 + 2 are equivalent.

The commutative property states that, when adding or multiplying numbers, the order in which they're added or multiplied does not matter. For example, 3 + 4 and 4 + 3 give the same result, as do 3 x 4 and 4 x 3.
What is the greatest common factor of 56 and 64?
| 8 | |
| 56 | |
| 39 | |
| 24 |
The factors of 56 are [1, 2, 4, 7, 8, 14, 28, 56] and the factors of 64 are [1, 2, 4, 8, 16, 32, 64]. They share 4 factors [1, 2, 4, 8] making 8 the greatest factor 56 and 64 have in common.
Convert y-3 to remove the negative exponent.
| \( \frac{-1}{-3y} \) | |
| \( \frac{1}{y^3} \) | |
| \( \frac{-1}{y^{-3}} \) | |
| \( \frac{-3}{y} \) |
To convert a negative exponent to a positive exponent, calculate the positive exponent then take the reciprocal.
