I would like to obtain the percentage of values in a nested dictionary of the form:

```
{'first': OrderedDict([('Jan', 2), ('Feb', 1)]), 'second': OrderedDict([('Jan', 3), ('Feb', 5)])}

```

The expected result should be like:

```
{'first': OrderedDict([('Jan', 40%), ('Feb', 16.6%)]), 'second': OrderedDict([('Jan', 60%), ('Feb', 83.3%)])}

```

The above result should be obtained as percentage: for the dictionary with key 'first':

```
Jan : 2/5 *100 = 40%
Feb: 1/6 *100 = 16.6%

```

For the dictionary with key 'second':

```
Jan : 3/5 *100 = 60%
Feb: 5/6 *100 = 83.3%

```
