Why does dividing a number by a fraction result in a quotient larger than the dividend?

Something positive less than one goes into a (positive) number more than that number of times. A fraction less than one goes into a (positive) number more than that number of times. Hence dividing by a fraction (less than one) increases the size of a number (whether that number is a fraction or not).

What happens when you divide a fraction by 2?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.

How do you divide fractions by fractions?

In order, the steps are:

  1. Leave the first fraction in the equation alone.
  2. Turn the division sign into a multiplication sign.
  3. Flip the second fraction over (find its reciprocal).
  4. Multiply the numerators (top numbers) of the two fractions together.
  5. Multiply the denominators (bottom numbers) of the two fractions together.

How to divide a fraction by another fraction?

To divide one fraction by another, you simply invert the divisor (invert means make the numerator the denominator and make the denominator the numerator) and multiply. For example 2/3 divided by 4/5 is the same as 2/3 times 5/4 which is 10/12 or 5/6 when reduced. Keep – Change – Flip?

How do equivalent fractions work?

The idea here is that a fraction is unchanged when you multiply both parts by the same quantity. This is covered in the posts How Do Equivalent Fractions Work?. If we multiply both numbers by the reciprocal of the divisor, the divisor becomes 1 and has no effect; while the new dividend is the product with that reciprocal.
