```

Returns tuple of multipliers.

`NonreducedRatio.``numbers`

Gets numbers of nonreduced ratio.

(2, 4)
```

Nonreduced ratio of three numbers:

```>>> ratio = abjad.NonreducedRatio((2, 4, 2))
>>> ratio.numbers
(2, 4, 2)
```

Set to tuple of two or more numbers.

Returns tuple of two or more numbers.

## Methods¶

`NonreducedRatio.``count`(argument)

Gets count of argument in ratio.

Returns integer.

`NonreducedRatio.``index`(argument)

Gets index of argument in ratio.

Returns integer.

## Special methods¶

`NonreducedRatio.``__contains__`(argument)

Is true when ratio contains argument. Otherwise false.

Returns true or false.

`(AbjadValueObject).``__copy__`(*arguments)

`NonreducedRatio.``__eq__`(argument)

Is true when argument is a nonreduced ratio with numerator and denominator equal to those of this nonreduced ratio. Otherwise false.

Returns true or false.

`NonreducedRatio.``__format__`(format_specification='')

Formats duration.

Set format_specification to ‘’ or ‘storage’. Interprets ‘’ equal to ‘storage’.

```>>> ratio = abjad.NonreducedRatio((2, 4, 2))
>>> print(format(ratio))
```

Returns string.

`NonreducedRatio.``__getitem__`(argument)

Gets item or slice identified by argument.

```>>> ratio = abjad.NonreducedRatio((2, 4, 2))
>>> ratio[1]
4
```

Returns integer or tuple.

`NonreducedRatio.``__hash__`()

Hashes non-reduced ratio.

Required to be explicitly redefined on Python 3 if __eq__ changes.

Returns integer.

`NonreducedRatio.``__iter__`()

Iterates ratio.

Returns generator.

`NonreducedRatio.``__len__`()

Gets length of ratio.

```>>> ratio = abjad.NonreducedRatio((2, 4, 2))
>>> len(ratio)
3
```

Returns integer.

`(AbjadObject).``__ne__`(argument)

Is true when Abjad object does not equal argument. Otherwise false.

Returns true or false.

`NonreducedRatio.``__rdiv__`(number)

Divides number by ratio.

```>>> 1 / abjad.Ratio((1, 1, 3))
[Fraction(1, 5), Fraction(1, 5), Fraction(3, 5)]
```
```>>> abjad.Fraction(1) / abjad.Ratio((1, 1, 3))
[Fraction(1, 5), Fraction(1, 5), Fraction(3, 5)]
```
```>>> 1.0 / abjad.Ratio((1, 1, 3))
[0.2, 0.2, 0.6]
```

Returns list of fractions or list of floats.

`(AbjadObject).``__repr__`()

Gets interpreter representation of Abjad object.

Returns string.

`NonreducedRatio.``__reversed__`()

Iterates ratio in reverse.

Returns generator.

`NonreducedRatio.``__rtruediv__`(number)

Divides number by ratio.

```>>> 1 / abjad.Ratio((1, 1, 3))
[Fraction(1, 5), Fraction(1, 5), Fraction(3, 5)]
```
```>>> abjad.Fraction(1) / abjad.Ratio((1, 1, 3))
[Fraction(1, 5), Fraction(1, 5), Fraction(3, 5)]
```
```>>> 1.0 / abjad.Ratio((1, 1, 3))
[0.2, 0.2, 0.6]
```

Returns list of fractions or list of floats.
