Yes
If you divide seven by nine, you get a repeating decimal of 0.77777777.
However, when you divide two by three, you also get a repeating decimal but smaller. 0.66666666
Yes. If you change the fraction of 2/3 to something with the denominator of 9, you can compare the numerators easily and directly.
You would do this by multiplying 2/3 by 3/3 to make 6/9, which is smaller than 7/9.
It is
It should be
In scientific notation,
So
Please see below.
.
There are infinite number of fractions that are equal to
You can multiply the numerator and denominator of
For example:
and so on and so forth.
To find the prime factorization of
Lets use these steps I found in here: https://www.wikihow.com/FindPrimeFactorization Follow along!
Step 1: Understand factorization. Hopefully you do, but just in case I'll explain.
Step 2: Know prime numbers. They are basically numbers that can only be factored by 1 and itself. e.g. 5 (
Step 3: Start with the number, which is
Step 4: Start by factoring the number into any two factors.
Step 5: If the factorization continues, start a factorization tree, so it is less vulnerable to mistakes.

Step 6: Continue factorization.
Step 7: Note any Prime numbers.
Step 8: Finish factorization. I already did this in the
Step 9: Finish by writing the line of prime factors neatly in increasing order.
we have
to find
we have the well known relationship
The other number is
For any questions involving HCF and LCM,find each number as the product of the prime factors. That will tell you what you are working with.
The other number cannot have
The other number is therefore
The prime factors of
The intention of the question is not absolutely clear....
Is it asking which of the factors of
Or
Is it asking for
It will help to write
Divide
The prime factors of
As the product of its prime factors:
There are many fractions which are equivalent to
To find an equivalent fraction, multiply
Multiplying the numerator and denominator by the same number does not change the value of a fraction.
When you divide
If
Then
And, of course, we have 3 of these divided pieces, giving us a total of
