## Video and Examples

This video will show you how to subtract fractions from a whole number. Sample

If you have a dollar, you can always cash it in for four quarters - it is an even exchange. This can be represented mathematically as .

Similarly, if you have 3 dollars, you can cash in one of those dollars for four quarters, leaving you with two dollars and four quarters - the same amount of money as 3\,=\,2\frac{4}{4}4\,-\,1\frac{2}{5}\,=6\,-\,4\frac{5}{8}\,=9\,-\,2\frac{1}{5}\,=9\,-\,2\frac{1}{5}\,=8\frac{5}{5}\,-\,2\frac{1}{5}\,=6\frac{4}{5}4\,-\,1\frac{3}{8}\,=4\,-\,1\frac{3}{8}\,=3\frac{8}{8}\,-\,1\frac{3}{8}\,=2\frac{5}{8}12\,-\,7\frac{2}{7}\,=12\,-\,7\frac{2}{7}\,=11\frac{7}{7}\,-\,7\frac{2}{7}\,=4\frac{5}{7}$$
