# Properties of Ratio

## Define and Prove

Consider equivalent ratios              then The Property is known as INVERTENDO. Now take ratios of first terms of both ratios to the second terms.  and  then The Property is known as ALTERNENDO
Now take the ratios of addition both the terms of one ratio to the second term.   and    then   The property is known as COMPONENDO. Now take the ratios of subtraction of both the terms of one ratio to the second term.  and  then The property is known as DIVIDENDO. Now take the ratios of addition of both the terms of one ratio to the subtraction of both term.   and    then  The property is known as COMPONENDO-DIVIDENDO.
