No. All fractions are not whole numbers, but all whole numbers are [improper] fractions (with a denominator of 1).
Yes, this is possible.
There are infinite possible answers, but 9/10, 95/100, 8/10, 88/100, etc. are all possible answers.
Fractions can only be added or subtracted if the denominators are the same. If the denominators are different, then the fractions need to be made into equivalent fractions with the same denominator. The new denominator can be found simply by multiplying the denominators together, but this can lead to some large fractions with which to work. A better new denominator is the lowest common multiple of (all the) denominators. (Once the new denominator is found, the fractions' new numerators are found by multiplying their current numerator by the new denominator divided by their current denominator to make their equivalent fractions with the new denominator.) Once all the fractions are converted into equivalent fractions with the new denominator then the fractions can be added or subtracted, with the result being simplified (if possible).
Equivalent fractions are multiples of the reduced fraction. 16/24 reduces to 2/3, so equivalent fractions would include 4/6, 6/9, 8/12, etc. Since you can multiple both the numerator and the denominator by any number, there is an infinite number of equivalent fractions possible.
It is not possible to list ALL the equivalent fractions because there is an infinite number of them.
Possible reasons: To add or subtract fractions, To compare fractions with different denominators.
Not at all, mass is measured in kilograms, and multiples or fractions of kilograms.
are all fractions are integers
They are all real numbers. All fractions can be expressed as percentages but not all percentages can be represented as fractions.
Reduce it, if possible.
to make them as simple as possible
It might have been possible to try to answer the question if you had provided the list of fractions. But since you could not be bothered to do so, I regret that it is not possible to answer the question.
No. All fractions are not whole numbers, but all whole numbers are [improper] fractions (with a denominator of 1).
If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.
Yes, this is possible.
No, it is quite possible for the fractions not to have common factors, even if you cross-cancel.
