What are compodendo and dividendo? |
| Answer» Componendo and dividendo are just a part of the mathematics calculation.Componendo and dividendo are greek words. According to it,If a/b = c/d , then (a+b) / (a-b) = (c+d) / (c-d).Let me give you proof for the above statement.Add 1 to both sides of the equation i.e., a/b + 1 = c/d + 1(a+b) / b = (c+d) / d ….i)Now,\xa0Subtract 1 from both sides of the equation i.e., a/b - 1 = c/d - 1(a-b) / b = (c-d) / d ….ii)Dividing eq. i) by ii). We get,(a+b) / (a-b) = (c+d) / (c-d) | |
