1/10, 2/10 and 7/10.
1/102/103/10
(1/10) + (3/10) + (6/10) = 1
by looking at the denominator
Answer: When adding or subtracting fractions with different denominators it is important to change the denominators into the lowest common denominator by using equivalent fractions. Answer: Equivalent fractions are used to: * Simplify fractions. It is sort of inelegant to write the final solution of a problem as 123/246, when you can just as well write it as 1/2. * Add fractions. If two fractions have different denominators, you need to convert them to equivalent fractions that have the same denominator. Only then can you add. * Subtract fractions (same as addition). * Compare fractions, to check which one is larger (same as addition).
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.
I have no idea what the "sum" of a fraction means.
1/10 , 3/10 , 6/10 . Their sum is (1+3+6)/10 = 10/10 = 1
1/102/103/10
(1/10) + (3/10) + (6/10) = 1

When adding or subtracting fractions with different denominators their lowest common denominator must be found first by using the LCM of their denominators
Unless you are using a calculator that adds them for you, it is much harder to add fractions with uncommon denominators. Having the same denominator allows you to only have to add the numerators for your answer.
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.
Use any three numbers whose sum is 10.For example, 1/10 + 2/10 + 7/10 = 10/10 = 1 or 3/10 - 9/10 + 2/10 = 10/10 = 1
There are 99999 fractions with a 1-digit numerator and 5-digit denominator - 6 digits in all: though not all the fractions are different. Similarly there are 8,999,910 fractions with a 2-digit numerator and 4-digit denominator. And so on. In total, there are 3,600,009 fractions using 6 numbers.
Different denominators: First, you find a common denominator (it can be the least common denominator, or any common denominator), and convert all fractions involved to equivalent fractions, using the common denominator. For example, 1/4 + 2/3. 12 is a common denominator; you can write this as 3/12 + 8/12.Same denominator: Just add (or subtract) the numerators, and keep the denominator. The above addition would become 11/12. Finally, you may want to check whether you can simplify the answer. Depending on how you (or the teacher) prefers the answer, you may also want to convert to a mixed fraction. In the above example, no such simplification is possible.
