Question

How do you divide `1/ 3\div 5`?

Answer 1

`1/5`

Explanation:

We can change this division problem by turning it into a multiplication problem:

We can use a method called "Keep, Change, Flip" or KCF.

This is to say that we keep the left fraction as is, change the division sign to a multiplication sign, and take the reciprocal of the right fraction.

Thus

`1/3divide5=>1/3times1/5`

Note: `5` is really a fraction with a denominator of `1` so it is written as `5/1`. It's reciprocal is then `1/5` which simply means that we flip the numerator and denominator.

So...

`1/3times1/5=1/15`
