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}$$
