Keep, change, flip! Dividing fractions is no problem when you have this mnemonic to guide you through the process.

Using ‘Keep, change, flip' is simple.
*
Keep
*
the first fraction as is,
*
change
*
the sign from division to multiplication, and
*
flip
*
the second fraction, putting the numerator on the bottom and the denominator on the top. Then multiply the two fractions to solve.

Step 3: Multiply.

Dividing by 2 and multiplying by

10 ÷ 2 = 5

The reciprocal of a fraction is its ‘flipped' counterpart--the denominator of one is the numerator of the other, and vice versa. The reciprocal of

Dividing by a fraction and multiplying by that fraction's reciprocal will always give you the same thing.
