Fraction division involves dividing one fraction by another. To do this, you can multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is created by flipping its numerator and denominator. For example, to divide 1/2 by 3/4, you would multiply 1/2 by 4/3. When multiplying fractions, you simply multiply the numerators together and the denominators together. In the previous example, 1/2 multiplied by 4/3 equals 4/6. This fraction can be simplified to 2/3 by dividing both the numerator and denominator by their greatest common divisor.
