The rectangle of blocks below represents what happens when $\frac{1}{4}$14 is multiplied by $\frac{1}{5}$15.

The sides of the rectangle both represent $1$1 and all of the blocks together make up $1$1 whole.

	$\frac{1}{5}$15
$\frac{1}{4}$14

Using the block representation, find the value of $\frac{1}{4}\cdot\frac{1}{5}$14·15.
