Yes, we can. And in most cases, they are easier than using mixed fractions.
By using the decimal numbers, you are now using the concept of fraction. There are some situation where we can apply the fraction, for example, cooking, medicine, sewing and tailoring :)
There is no such example. If you cannot use an exact fraction then there will not be an exact decimal that you can use instead. And, if you are using an approximate decimal, you could use an approximate fraction instead.
A half life may or may not be a fraction. The half life of carbon 14, for example, is 5715 years - not really a fraction, unless you are thinking in terms time periods which are much longer than a year.
compare with random fraction to a benchmark fraction. to tell if a fraction is less or greater than another fraction.

ok pretend u made a cake and u want to share it with ur family(4 people).what fraction do u have when u cut it for the people and u.

340 is an integer, not a fraction. But, if you had to write it as a fraction, you could use 340/1.

You use a reciprical in dividing fractions. 1st you write down the problem. then you flip over the 2nd fraction and multiply the 1st fraction with the second fraction, and there is your answer,
You need fractions for cooking. You use measuring cups and spoons that are sized exactly so you can add half a cup of flour or half a teaspoon of salt to your recipe.

There is no need to do so.
Divide the numerator by the denominator.
