When they are equivalent ratios.
Two ratios are equivalent if their simplest forms are the same.
One to two Two to four They're known as equivalent ratios.
You can use ratios of adjacent sides to prove if two rectangles are similar by comparing to see if the ratios are the same
No. The chemical formulas for the two compounds would be different as the ratios were different. For example there are three different oxides of iron which obviously contain the same two elements but these are in different ratios:- FeO Fe3O4 Fe2O3
When both can multiply its comparisons to when both ratios share the exact same numbers.
If two ratios have the same value when simplified.
The simplified forms of the two ratios are the same.The cross products are the same: a/b = c/d if ad = bc
