Best Answer

To add fractions, you cannot simply add the numberators and add the denominators.

To add fractions, they must first have the same denominator. Once they have the same denominator, you can then simply add the numerators.

it means to leave the denominators the same and add the numerators

Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

False [ I THINK ]

When adding fractions with like denominators, add the numerators together and put the result over the denominator. Simplify if possible.

Probably the most common use is in adding fractions with different denominators. The least common multiple of the denominators is the least common denominator. Each fraction can be converted to one with the common denominator, and then you can add the fractions by adding their numerators.

The denominators must be the same, the numerators can be different.

to add a fraction, get a common denominator, then add the numerators. example: 2/10+4/5 first get common denominators 2/10+8/10 then add the numerators 10/10 (simplify) 1 to subtract from a fraction, get common denominator, then subtract the numerators. example: 4/5-2/10 first get common denominators 8/10-2/10 then subtract the numerators 6/10 (simplify) 3/5

I learned to always change the denominators before adding or subtracting the numerators. You must always have a common denominator before adding or subtracting.

Adding and subtracting fractions can ONLY be done if the denominators are the same; then the calculation is done by adding or subtracting the numerators. Multiplying (and dividing) fractions does not require the denominators to be the same. To divide by a fraction the divisor is inverted (the original numerator becomes the new denominator and the original denominator becomes the new numerator) and then the fractions are multiplied. Multiplying fractions is achieved by multiplying the numerators together AND multiplying the denominators together. A whole number is the same as a fraction with the whole number as the numerator and a denominator of 1, so when multiplying by a whole number the denominator is multiplied by 1 (leaving it the same) and the is multiplication is effectively just multiplying the numerator by the whole number.

The trick to adding fractions is three simple steps. First, make sure the bottom numbers (the denominators) are the same. Secondly, add the top numbers (the numerators), put the answer over the denominator. Finally, simplify the fraction if need be.

Sum of the fractions = sum of numerators divided by their common denominator. Adding Fractions rule implies to addition of fractions having same denominator and as well as adding fractions with different denominators. So rule for adding fractions having the same denominator is add the numerators and simplify For example : 3/5 + 2/5 + 9/5 = (3 + 2 + 9)/5 [add the numerators] = 14/5

If the denominators are not the same then yes.If the denominators are the same you can simply add the numerators:1/5 + 2/5 = 3/5because the denominators are all the same, and 1 + 2 = 3.If the denominators are different, simply adding the numerators will give the wrong answer:1/5 + 2/3 3/5 or 3/3.Instead, find the Least Common Multiple of the denominators (15 in this case) and convert both fractions to that denominator. Then you can go back to simply adding the numerators.1/5 = 3/152/3 = 10/153/15 + 10/15 = 13/15because 3 + 10 = 13.
