In common usage, no. The multiples of a number refers to all its WHOLE number multiples. Otherwise any other number is a multiple and the term simply means the set of all numbers.
It is not: they are the same. A "product" and "multiple" are synonyms.
Same as adding, multiplying, and dividing.
Find the equivalent fractions with the same denominator (the least common multiple) and then compare the numerators.
If the fractions do not all have the same denominator, find a common multiple of the denominators (ideally the lowest common multiple) and convert the fractions to equivalent fractions with this denominator. Now with all the fractions with the same denominator, add together the numerators. Finally, reduce the fraction to simplest terms, converting any improper fraction to a mixed number.
You convert them to equivalent fractions each of whose denominators are the same - either the lowest common multiple (LCM) of the original denominators or a multiple of the LCM.
Because when adding or subtracting fractions the denominators must have the same values
-- All proper fractions are not equal to 4.12 , -- Of the infinite supply of improper fractions, all of them are not equal to 4.12 except only 103/25 and other ratios of (a multiple of 103)/(the same multiple of 25).
I think what you mean is equivalent fractions. It means two fractions that are equivalent, or the exact same.
Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
They are essentially the same. A common denominator is the common multiple of a set of denominators of a set of fractions.
There doesn't appear to be any fractions there but to find the LCD of fractions is done in the same way as finding the lowest common multiple of numbers.
