Example Question #1 : Find The Area Of A Rectangle With Fractional Side Lengths By Tiling: Ccss.Math.Content.5.Nf.B.4b

By tiling a rectangle with unit squares, find the area of a rectangle with a length of  of an inch and a width of  of an inch.

Explanation:

To set up a tiled area model to solve the problem, we use the denominators for the dimensions of our area model, and we use the numerators to fill parts of the area model.

We make the area model  by  because those are the denominators of our fractions. We shade up  and over , because those are the numerators of our fractions. Our answer is a fraction made up of the boxes that are shaded (the numerator) and the total tiles in the area model (the denominator).

Notice that we could have multiplied the numerators of our fractions and the denominators of our fraction to find our answer.
