to make your denominator common you have to times a number that equals the same
Find the least common denominator and convert them to equivalent fractions so that the denominators are the same. Choose the one with the greatest denominator.
When a fraction is simplified, it is made into an equivalent fraction with no common divisor between the numerator and denominator.
You don't need a common denominator to divide fractions.
Same as for addition. Mainly, you have to convert the fractions to equivalent fractions that have the same denominator. After that, it is easy: just subtract the numerators and put the result on top of the common denominator.
The first step, to add, subtract, or compare fractions, is always to convert the fractions to equivalent fractions, that all have the same denominator. You can use one of several techniques to get the LEAST common denominator, or simply multiply the two denominators to get a common denominator (which in this case may, or may not, be the smallest common denominator).
In order to have a greatest common denominator, there has to be two numbers and they both have to be fractions. 60 has no greatest common denominator.

You look for a common denominator; convert the fractions to equivalent fractions with the denominator you found; then you do the addition itself.
Get each fraction to have a common denominator, and then sort the fractions from least to greatest based on the numerators.
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.
If you are adding or subtracting unlike fractions, convert them to equivalent fractions with a common denominator.
You first convert them to equivalent fractions with a common denominator. Or you convert them to decimal fractions.
Find the least common denominator and convert them to equivalent fractions so that the denominators are the same. Choose the one with the greatest denominator.
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.
When a fraction is simplified, it is made into an equivalent fraction with no common divisor between the numerator and denominator.
The greatest common factor is the largest number that is evenly divisible by both numbers, so if you divide both numerator and denominator by GCF, the numerator and denominator will be the smallest integers possible, and still be an equivalent fraction.
