When is it useful to find the LCM or GCF of two numbers to solve a problem?
When adding or subtracting fractions with different denominators and when reducing fractions to their lowest termsWhen adding or subtracting fractions with different denominators their lowest common multiple is needed and when reducing fractions to their lowest terms their greatest common factor is needed.
How do you know whether to use common factors or multiples to solve a problem?
The hcf is useful in reducing fractions to their lowest terms and the lcm is useful in finding the lowest common denominator of fractions that have different denominators that need to be added or subtracted.
When would it be useful to know the common factors or the greatest common factor of two or more numbers?
When you need to reduce fractions to their simplest form.
What the difference between like and unlike fraction?
fractions having same denominators are like fractions & others are unlike fractions
What are the rules of the dissimilar fractions?
I assume you mean, with different denominators. If you want to add the fractions, subtract them, or compare them (determine which one is greater), you have to convert them to similar fractions (fractions with the same denominator) first. Converting to similar fractions is not necessary, and usually doesn't even help, if you want to multiply or divide fractions.
How are common factors useful?
They are useful in reducing fractions and to simplify radicals. They are useful in reducing fractions and to simplify radicals.
Are fractions useful in building?
Yes.
How is the prime factorization useful?
It helps to reduce fractions.
When is it useful to know multiples of a number?
When reducing fractions to their lowest terms or finding the LCD of fractions
Why is finding the greatest common factor is useful for fractions?
It allows you to add and subtract the fractions with greater ease.
Why do you find LCM and HCF?
When simplifying fractions it's useful to know what is the HCF of the numerator and denominator is. When adding or subtracting fractions with different denominators it's useful to know what the LCM of them is.
Why are fractions famous?
The are important and useful but I would not say that they are famous!

Why is integers useful?
Integers are whole numbers without decimals or fractions which are useful because calculations are easier to work out.
Why is finding prime factorization of a number useful?
It helps to reduce fractions.
Why is finfing the prime factorization of a number useful?
It helps to reduce fractions.
How is being able to compare fractions useful?
All you have to do is to figure how you have to equal them.
