Having a strong number sense of fractions enables individuals to recognize and manipulate fractions more easily, which is crucial for estimating sums. It allows for quick mental calculations by simplifying fractions to their nearest benchmarks, such as 0, ½, or 1. This skill helps in rounding fractions to make them easier to work with, facilitating faster and more accurate estimations without the need for precise calculations. Overall, a solid grasp of fractions enhances the ability to make educated guesses and check the reasonableness of answers.
The answer depends on which fractions you consider as benchmarks.
Benchmark fractions are common fractions that you can judge other numbers against. Normally, 1/4, 1/2, 3/4, and often 1/10 (because of its relationship with decimals) are refered to as benchmark fractions. Estimation is a perfect example of how a benchmark fraction is used. If you are measuring the length of an object, and it is 3 9/32 inches, you are most likely to say 3 1/4 inches, instead of rounding down to 3 inches, or getting a more precise measurement of 3 9/32. By far the most common benchmark is 1/2. In rounding a number, 1/2 is the difference between going up to the next number, or rounding off to the last number. In many cases, problems that use the standard measurement system will ask that an object be measured to the nearest 1/2 unit (1/2 inch, 1/2 cup) This is not as common with metric units, since they are a base 10 system, but you may see some 1/2 liter or 1/2 kilometer measurements.

By rounding each of the numbers involved.
In mathematics, particularly when working with fractions, a benchmark refers to a commonly used reference point that helps in estimating or comparing the size of fractions. Common benchmarks include fractions like 0, 1/2, and 1, which can be used to determine whether a given fraction is less than, greater than, or approximately equal to these values. Using benchmarks aids in visualizing and understanding the relative size of fractions in various contexts.

There are infinitely many such fractions and the answer also depends on which other benchmarks you are using.
Benchmark Decimals are fractions (decimals) like 0 1/2 1/4 .25 .50 .75 like that!
what fractions?
Fractions help with numbers that are not whole numbers.
It is not clear why you would wish to add them! Changing them to fractions is generally the better option because it averts rounding errors.
