Question 226507
<font face="Garamond" size="+2">


I presume you are trying to represent mixed numbers rather than show multiplication of each of the fractions by 2.  Hence you are trying to represent:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2\frac{5}{2}\ -\ 2\frac{3}{2}\ =^?\ 2\frac{3}{2}]


The simple answer is, <b><i>no</i></b>, the two expressions are <b><i>not</i></b> equal.


Convert the mixed numbers to improper fractions:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2\ =\ \frac{4}{2}], so


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2\frac{5}{2}\ =\ \frac{4}{2}\ +\ \frac{5}{2}\ =\ \frac{9}{2}]


Similarly:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2\frac{3}{2}\ =\ \frac{4}{2}\ +\ \frac{3}{2}\ =\ \frac{7}{2}]


So:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2\frac{5}{2}\ -\ 2\frac{3}{2}\ =\ \frac{9}{2}\ -\ \frac{7}{2}\ =\ \frac{2}{2}\ =\ 1\ \neq\ 2\frac{3}{2}]
