Select ALL fractions that are equivalent to -4/9.

1 answer

To find fractions that are equivalent to \(-\frac{4}{9}\), you can multiply both the numerator and the denominator of the fraction by the same non-zero integer. Here are a few examples:

  1. Multiply by \(2\): \[ -\frac{4 \times 2}{9 \times 2} = -\frac{8}{18} \]

  2. Multiply by \(3\): \[ -\frac{4 \times 3}{9 \times 3} = -\frac{12}{27} \]

  3. Multiply by \(-1\): \[ -\frac{4 \times -1}{9 \times -1} = \frac{4}{9} \] This is not equivalent as it's the positive version.

  4. Multiply by \(-2\): \[ -\frac{4 \times -2}{9 \times -2} = \frac{8}{18} \]

The general form of an equivalent fraction to \(-\frac{4}{9}\) is: \[ -\frac{4k}{9k} \] where \(k\) is any non-zero integer.

Thus, some examples of equivalent fractions to \(-\frac{4}{9}\) include:

  • \(-\frac{8}{18}\)
  • \(-\frac{12}{27}\)
  • etc.

Any fraction in the form \(-\frac{4k}{9k}\) with non-zero \(k\) will be equivalent to \(-\frac{4}{9}\).
