How can you divide a fraction by a fraction

1 answer

Dividing a fraction by another fraction involves a simple process. Here are the steps:

  1. Keep the First Fraction: Write down the first fraction (the one you are dividing).

  2. Change Division to Multiplication: Change the division sign to a multiplication sign.

  3. Flip the Second Fraction: Take the second fraction (the one you're dividing by) and flip it. This is known as finding the reciprocal of the fraction.

  4. Multiply: Multiply the first fraction by the reciprocal of the second fraction.

  5. Simplify (if necessary): If possible, simplify the resulting fraction.

Example

Let's say you want to divide \( \frac{2}{3} \) by \( \frac{4}{5} \):

  1. Keep the First Fraction: \( \frac{2}{3} \)
  2. Change Division to Multiplication: \( \frac{2}{3} \times \)
  3. Flip the Second Fraction: The reciprocal of \( \frac{4}{5} \) is \( \frac{5}{4} \).
  4. Multiply: \[ \frac{2}{3} \times \frac{5}{4} = \frac{2 \times 5}{3 \times 4} = \frac{10}{12} \]
  5. Simplify: \( \frac{10}{12} \) can be simplified to \( \frac{5}{6} \) by dividing both numerator and denominator by 2.

So, \( \frac{2}{3} รท \frac{4}{5} = \frac{5}{6} \).
