What is the least common denominator of 160?
You need at least two denominators to find an LCD.
Explain how comparing fractions with like denominators differs from comparing fractions with unlike denominators?
Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).
What are the steps in finding the least common multiple of two numbers?
to find the least common multiple of two numbers you must list the factors then you can find out their least common multiple of the two numbers
The common denominator 32?
You need at least two denominators to find something in common between them. If that's 3 and 2, the common denominator is 6..
What is the least common multiple of 108?
You need at least to numbers to find a least common multiple.
When adding mixed numbers what number are you supposed to find the least common multiple?
the denominators
How would you add two mixed numbers together if they have different denominators that don't go into each other?
Find the least common multiple. For example, if the denominators were 6 and 7, the least common multiple would be 42.
What is the least common denominator of 169 only?
You need at least two denominators to find something in common between them.
How do you add and subtract rational numbers with unlike denominators?
You first find equivalent fractions whose denominators are a common multiple of the different denominators. Teachers like you to use the least common denominator: that is not necessary although it can result in your working with smaller numbers and so make things easier.
What way is subracting fractions with unlike denominators like adding fractions with unlike denominators?
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.
Discuss the possible advantages and disadvantages of using least common denominators when adding and subtracting fractions?
By using least common denominators when adding and subtracting fraction you get small numbers which are easy to perform operations on. On the other hand if you deal with common denominators which are excessively large, then you will find that operations are harder to perform. The one disadvantage of using LCD is that they can occasionally be difficult to find.
How can you get a dcommon denominator?
You can multiply the two denominators, or you can find the least common multiple for the two denominators.
How does the least common multiple of two numbers help you add fractions?
When adding unlike fractions, find the LCM of the denominators and convert them to it.
What is the greatest common denominator of 12.375?
You need at least two numbers to find something in common between them. The greatest common denominator of any set of denominators is infinite.
How do you do least common denominators?
Find the LCM of the denominators. Since the LCM of 3 and 4 is 12, the least common denominator of 1/3 and 1/4 is 12.
What is the least common denominator of 160?
You need at least two denominators to find an LCD.
What is the least common denominator of 120?
You need at least two denominators to find something in common between them.
