When performing arithmetic operations with fractions, the nimittäjä plays a key role. To add or subtract fractions, they must have a common nimittäjä. This is achieved by finding a common multiple of the original nimittäjät and adjusting the numerators accordingly. Multiplying fractions involves multiplying the numerators together and the nimittäjät together. Dividing fractions is equivalent to multiplying the first fraction by the reciprocal of the second fraction, which means inverting the second fraction and swapping its numerator and nimittäjä. The concept of the nimittäjä is fundamental in mathematics and appears in various fields beyond basic arithmetic, including algebra and calculus.
