## Step 1: Reciprocate the Second Fraction

To divide fractions we first need to reciprocate the second fraction(See first image).

This just means we switch the positions of the numerator(top number) and denominator (bottom number) (See second image).

Then, after reciprocating the fraction we need to change the divide sign to a multiply(See third image).

In this example using 1/2 / 1/3, we are left with 1/2 X 3/1.

## Step 2: Do the Multiplication

Now all you have to do is the multiplication(See image).

If you don't know how to multiply fractions, then check out my other instructable called Multiplying Fractions. Remember to simplify your result if necessary. If you cross-cancel the multiplication, (again, see Multiplying Fractions) remember that you must cross cancel **AFTER ** you convert the divide to multiply, **NOT** before!!!

is the answer to the first one 42/32

My school says keep flip switch

U keep first number ,switch it to multiplication, and switch the 2nd fraction

I still don't get it because all of my math problems are different.

A way to remember is "kiss 'n' flip". You kiss (x from xoxo) then you flip the fraction on the right.

nice job on the win, beat me :D
