Cross Production

Preview

Cross production is used in division and is like a shortcut to finding quotients in fractions. So since cross production is used in fractions we need two fractions so let's take the fractions:
6  /  7
8     9
So what you need to know is that when you are doing cross production you are actually multiplying and you are multiplying one numerator by the other denominator and multiplying a numerator by a denominator again so we will do something like this:
6 / 7
8   9

6x9=54
8x7=56

So now we have to write the fraction out by putting the numerator on top and denominator on bottom like this:
54
56
So this is how you do cross production and if you want at the end you can simplify the fraction. Now try some of these and make sure to watch the video on YouTube.
