Off the top of my head, I think you want something like

```
<div class="solution" data-type="multiple"><span class="sol" data-forms="integer, decimal, improper, mixed" data-inexact data-max-error="0.09"><var>...</var></span><code>&deg; C</code></div>
```

An example would be adding_and_subtracting_decimals_word_problems.html
