Because not all measurements can be expressed as an integer multiple of some base measurement.
There is no such number. Given any number, there is sure to be an important fraction that is smaller.
it is important for us to learn to a decimal as a fraction because if you don't understand the way you write it in decimals you can change it into a fraction to understand it properly
It is not particularly important.
It is no more important than in other activities.
All fractions are important. Perhaps you mean improper fraction, where the numerator is greater than or equal to the denominator, like 22/7
It is NOT particularly important. It all depends on what form you prefer to work with.
Because your answer goes on the right
yes because if there were no fractions there will be nothing.
i dont know i asked it
From a mathematical point of view, it is not at all important. Any equivalent fraction is just as good, so simplification makes no difference whatsoever. However, the simplest form involves the smallest integer values for the fraction and most people find it easiest to understand and to work with small numbers. Also, examiners expect you to be able to simplify fractions.
Reciprocal just means that you flip the fraction... your fraction is -p/4 the reciprocal is 4/-p the reciprocal is extremely important when dividing fractions. because when you divide fractions you have to take the reciprocal of the bottom fraction and then multiply it to your top fraction to get your answer.
It is the reflectivity of the surface. However, it is important to note that the reflected fraction depends on the wavelength of the incident light.
