# RatioEqual

Check if two lists are equal as ratios

Contributed by: Wolfram|Alpha Math Team
 ResourceFunction["RatioEqual"][list1,list2,…] returns True if all of the listi are equivalent as ratios.

## Details and Options

Two lists are equivalent as ratios if they have the same length and quotients of corresponding elements all give the same result.
ResourceFunction["RatioEqual"] treats input decimals as exact representations of their rational equivalents. The rational representation of a decimal x is computed as FromDigits[RealDigits[x]].

## Examples

### Basic Examples (2)

Test if two lists are in the same proportion:

 In[1]:=
 Out[1]=

Order matters in the comparison of the lists as ratios:

 In[2]:=
 Out[2]=

### Scope (2)

Test if two ratios involving real and rational numbers are equivalent from a mathematical perspective:

 In[3]:=
 Out[3]=

Two ratios with symbolic numbers can be equivalent:

 In[4]:=
 Out[4]=
