It's the same process as finding the least common multiple.
Example: 7/30 + 13/42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Combine the factors, eliminating duplicates.
2 x 3 x 5 x 7 = 210, the LCM
Since 210 is the lowest common denominator, we can proceed to add them.
7/30 = 49/210
13/42 = 65/210
7/30 + 13/42 = 114/210 or 19/35 in lowest terms.

How do you compare dissimilar fraction?
Find the least common denominator.
How do you find an equivalent fraction for a fraction by using the least common denominator?
you find the highest number that goes into both the numerator and the denominatior and divide both by that number.
How do you rename dissimilar fraction to similar fraction?
Find the least common denominator and convert each fraction to its equivalent. Example: 2/3 and 3/4 The least common denominator of 3 and 4 is 12. 2/3 = 8/12 3/4 = 9/12
How can you change disimilar fraction to similar fraction?
Find a common denominator.
How to change dissimilar fractions to similar fractions?
Note: numerator is the top part of the fraction, denominator is the bottom part. 1) Find a common denominator. It may be the least common denominator, but it need not be; just multiplying the denominators also gives you a common denominator, not necessarily the smallest one. 2) Convert each fraction so that it has this common denominator. This means multiplying numerator and denominator by the same number.
What is the least common denominator of 19over20?
That's one fraction. You need at least two to find something in common between them.
How do you compare dissimilar fraction?
Find the least common denominator.
What is the common denominator of 84 out of 100?
84/100 is one fraction. To find a common denominator, you need at least one more.
What is the least common denominator of one sixth?
You need at least two denominators to find something in common between them.
Why if there are two fraction having different denominator are you are going to find first their least common denominator?
To get the right answer when you add or subtract them.
Write a proper fraction with a denominator that is common to 7and 8?
To find a common denominator for 7 and 8, we need to find the least common multiple (LCM) of the two numbers, which is 56. Therefore, a proper fraction with a denominator that is common to 7 and 8 would be any fraction with 56 as the denominator, such as 3/56 or 7/56.
How are equivalent fractions used when subtracting unlike fractions?
First you find a common multiple of the denominators. The least common denominator is handy but not essential. This number will be the denominator of the answer - before simplification.For both fractions find an equivalent fraction whose denominator is this common denominator.Carry out the subtraction on the new numerators to give the numerator of the answer.Simplify the result for the final, simplified answer.First you find a common multiple of the denominators.

What does least common denominators mean in math?
The denominator is the bottom number in a fraction. If you had two fractions, and were asked to figure out the least common denominator, you'd have to find the smallest number both of the denominators go into.

What is the least common denominator of 9?
You need at least two numbers to find a common denominator.
How can equivalent fractions help when adding mixed numbers?
It can help by when finding the LCD (Least Common Denominator) you find the least number they have in common then that number is your equivalent fraction.
