Remember that a division equation can be written as a fraction with the divisor as the denominator and the dividend as the numerator. So, 15 divided by 13 can be written as 15/13, which can be simplified to a mixed number of 1 2/13.​

We are looking for how many servings can be made from 6 pints. The serving size is 1/3 pint. So I need to know how many 1/3's can fit into 6. We can use a model, or we can use our algorithm and use the inverse operation and inverse of the divisor. Watch the video for both strategies.​

This is a two step problem. First we need to figure out how many acres of land will be used for lots. We started with 24 acres, but he used 6 acres for the entrance so only 24-6 = 18 acres are available for the lots. Next we need to figure out how many 1/3 acre lots are in 18 acres. So our equation would be 18 divided by 1/3. Watch the video for a model and algorithm strategy.

Explanation #3

​

We start with only 1/2 of a cake, and want to know how much of the whole cake each person will get if 4 people share 1/2 a cake. Our equation is 1/2 divided by 4. The model is a bit different for a fraction divided by a whole number, but the algorithm follows the same steps of using the inverse operation and inverse divisor. Watch the video for the strategies.
