Lesson

Now that we have seen how to divide a fraction by a whole number, it's just one more step to be able to divide any fraction by a whole number. We're still *sharing* our fractions, but we are starting with a larger part of something. It's handy to remember the reciprocal of a number, as we'll be using that to solve our problems.

Let's see how we can divide our fraction by a whole number, in this video.

The rule

When you need to divide a fraction by a whole number, you can multiply the fraction by the reciprocal of the whole number.
