🔎 What is the Keep Change Flip Method?

The Keep Change Flip (KCF) method is a simple strategy for dividing fractions:

Keep – Keep the first fraction exactly as it is.

Change – Change the division sign to multiplication.

Flip – Flip (take the reciprocal of) the second fraction.

Example:

2
3
÷
4
5
3
2
​

÷
