Vedic Maths - Ratios

To Simplify ratios we divide each one by its highest common factor.
So 24:6 is equal to 4:1 as 6 X4 = 24. So every ratio which is not a simplest ratio can be simplified to a simplest ratio.
Sometimes we have to increase a ratio to get whole numbers:-
1.5/2.5 = 3/5.
Splitting into a ratio.
If we want to split £20.00 into the ratio 3:1, we get 15:5. We first add the ratios to get 4, then divide 20/4 = 5. Then we multiply out to get 15:5.
