i think divisibility rules help with fractions because it helps you reduce the fraction to make i a simple fraction.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Why do you need HCF and LCM?

The LCM will help you add and subtract fractions. The GCF will help you simplify fractions.


Why you need LCM and HCF in maths?

The LCM will help you add and subtract fractions. The GCF will help you simplify fractions.


How divisibility rules can help you find common factors?

Divisibility rules help you find the factors of a number. Once you've found the factors for two or more numbers, you can find what they have in common. Take 231 and 321. If you know the divisibility rules, you know that they are both divisible by 3, so 3 is a common factor.


How can knowing the divisibility rules help to determine if a number is prime or composite?

Knowing the divisibility rules will help you by being able to recognize if a number has factors (other than one and itself) which are covered by the rules. This will save actually having to start doing divisions.


Why is the GCF important?

Finding the GCF will help you to simplify fractions.


Why is it important to know the GCF?

The GCF will help you to simplify fractions.


How can divisibility rules help you to find the prime factorization of 53?

The divisibility rules will show that 53 is not divisible by anything other than 1 and itself. Since it is already prime, it doesn't have a factorization.


How does knowing factors help you simplify fractions?

Knowing factors will help you find a GCF. To simplify a fraction, divide the numerator and the denominator by their GCF.


How can divisibility rules help you?

It helps you not to put the wrong answer and it helps you to not write anything down.


How understanding factors help to write divisibility rules?

Factors of numbers are divisible by them with no remainders

How can the GCF help you with fractions?

Finding the GCF of the numerator and the denominator and dividing them both by it is the way to simplify a fraction.


How can the divisibility rules help find prime factorization?

You can test successive prime numbers to see if your number is divisible by them, but knowing the divisibility rules will help you eliminate some steps, depending on what your number is. If your number is odd, you don't have to test for 2. If the sum of your number's digits do not total a multiple of 3, you don't have to test for 3. If your number doesn't end in a 5 or 0, you don't have to test for 5. Just by looking at your number, you can include or eliminate the three most common primes if you know the rules of divisibility.


Friendly number strategy for divisibility?

I've never heard of a "friendly number strategy" per se; but there are specific rules for "divisibility" that you can use to help break up large numbers. For example, if the number is even, it is divisible by 2; if the sum of the numbers


How can your knowledge of divisibility rules help you to determine whether a number is prime or composite?

If a number is divisible by anything other than itself and 1, it's composite.


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 can you determine whether one number is a factor of another?

Knowing the rules of divisibility will help. Also, if you divide the smaller number into the larger one and the answer is an integer, it's a factor.


How can knowing the greatest common factor and lowest common factor help when you add subtract and multiply fractions?

The least common factor of any set of numbers is 1, so that doesn't help at all. Finding the GCF of the numerator and denominator and dividing them by it will help to simplify a fraction. Finding the least common multiple of the denominators (called the least common denominator) will help when you add and subtract fractions. None of those are needed to multiply fractions.


How can using the GCF and LCM help you when you add subtract and multiply fractions?

When adding and subtracting unlike fractions, it is necessary to find a least common denominator. It's the same process as finding an LCM. You can simplify a fraction by finding the GCF of the numerator and denominator and dividing them both by it.


How do divisibility rules help you find factors of a number?

If you know that a number is divisible by three, then you know that three and the number that results from the dividing are both factors of the original number. If you know that a number is not divisible by three, then you won't waste time performing that function. It's rare that the first factor other than one isn't a number between two and ten. If you know the divisibility rules, it will make factoring easier and faster.


How divisibility rules can help you find the prime factorization?

Suppose you were trying to find the prime factorization of 123. You know that half of the divisors will be less than the square root. Since the square root is between 11 and 12, you only need to test 2, 3, 5, 7 and 11 as prime factors. If you know the rules of divisibility, you already know that 2 and 5 aren't factors and 3 is. It saves time.
