Yes you do.
You first convert them to similar fractions, i.e., to fractions that have the same denominator.* Step one: find a common denominator.* Step two: convert both fractions to equivalent fractions that have that denominator.
Find a common denominator, (best is the LCM) Convert both fractions into a form with a common denominator Add numerators, keep sam common denom. Reduce.
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.
find a common denominator. Then just add across.
Only if the denominators are different.
You Ned to find a larger common denominator or multiply the denominators to gain a common denominator.
just find a common denominator and add like you regularly would with fractions.
Find a common denominator, add the numerators, simplify if possible.
There isn't a universal answer to all problems. What you should try to do is find the lowest common denominator between the fractions you are adding.
Common Denominator means that the denominators in two (or more) fractions are common, or the same. The common denominator is important because before you can add or subtract fractions, the fractions need to have a common denominator.Sometimes fractions have different denominators, like 2/3 and 3/4. If you want to add or subtract them, they need to have the same denominator. In order to do that, you find a common denominator which is the same thing as a common multiple, only with denominators.
Find their least common denominator and convert them.
To add and subtract fractions, you need common denominators. To find the common denominator, find the LCM of the denominators you wish to add or subtract.
