### Fractions Explained - Fast

Fractions Explained - Fast

The hardest thing about learning fractions is adding them. Multiplication is easy, but addition is usually taught as a complex multi-step process. It's a real pain.

But it doesn't have to be that way. Take the two fractions to be added..

a c
-+-
b d

Take the diagonal numbers (top left and bottom right) and multiply them, a*d

Do the other diagonal, c*b

That's the "top" (numerator) of the answer.

The "bottom" (denominator) of the answer is much easier, it's just b*d

You're done!

Did you notice the pattern? It's two diagonals and a base, like this..

X
_

A lot of mathematics involves patterns.

To multiply fractions just multiply the tops and multiply the bottoms. So..

a c
-*-
b d

is (a*c)/(b*d)

That's it. Fractions done in a few minutes. With the time saved why not study more interesting math topics!
