Thanks Alan,

or you could just do it on the site calc

you use the divide by sign as a fraction line.

$$\left({\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{2}}}{{\mathtt{5}}}}\right){\mathtt{\,\small\textbf+\,}}\left({\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{4}}}}\right) = {\mathtt{4.65}}$$

I did this using the "Math (Input=Result)" button on the ribbon.

If you do it on the actual calculator and hit the = sign again it will give it to you as an improper fraction.

Unfortunately you have to do more work to turn it into a mixed numeral.

$$2\frac{2}{5}+2\frac{1}{4} = 2+\frac{2}{5}+2+\frac{1}{4} = 4+\frac{2}{5}+\frac{1}{4}$$

Collect the fractions over a common denominator:

$$\frac{2}{5}+\frac{1}{4} = \frac{2*4}{20} + \frac{1*5}{20} = \frac{8+5}{20} = \frac{13}{20}$$

So, altogether   $$2\frac{2}{5} + 2\frac{1}{4} = 4\frac{13}{20}$$
