we use this because it is easier and it shows you what to do for example 2/4 is eqivalent to 1/2. 2 divided into 2 is one and 4 divided into 2 is 2 so it is 1/2.

When you multiply fractions which reciprocal do you use?
None. Multiply numerator by the numerator and denominator by denominator.
How can you use decimals instead of fractions?
To convert a fraction to a decimal, divide the denominator into the numerator.
What improper fraction is equal to 5 1.2?
It is 21/4... You take the whole number, multiply it by the Denominator and add the top number which is the Numerator... and use the current denominator and use it as the improper fractions denominator...
How could you use the relationship between the numerator and denominator of fractions equivalent to one half to determine if a fraction is less than one half?
If the denominator is more than double the numerator, then the fraction is less than a half.
How coule you use the relationship between the numerator and denominator of fractions equivalent to one-half to determine if a fraction is greater than one-half?
In fractions equivalent to 1/2, the numerator is half of the denominator. Any fraction where the numerator is less than half of the denominator, like 19/40, is less than 1/2. Any fraction where the numerator is more than half of the denominator, like 49/96, is greater than 1/2. That's also a quick way to compare fractions. 4/9 is less than 5/8.

The denominator must be double the numerator.
How do you convert fractions and whole numbers into decimals in the easiest way?
The easiest way is to take a calculator, and divide the numerator by the denominator. If you are not supposed to use a calculator, divide the numerator by the denominator on paper.
How do you order fractions with unlike denominators?
You can convert them to equivalent fractions with like denominators, then simply compare the numerators.You might also convert each fraction to a decimal (divide the numerator by the denominator); then you can also compare them.

It is 21/4... You take the whole number, multiply it by the Denominator and add the top number which is the Numerator... and use the current denominator and use it as the improper fractions denominator...
5 examples of rational numbers?
Just write any five fractions, with integers (whole numbers) in the numerator and the denominator. Don't use zero as a denominator.
What are three rules you can use to compare fractions?
Rule #1 When two fractions have the same denominator, the bigger fraction is the one with the bigger numerator. Rule # 2 When comparing fractions that have the same numerator, the bigger fraction is the one with the smaller denominator. Rule # 3 You can convert the fractions and then just put the greater than, less than or equal to sign to see what the comparison is between the fractions.
How could you use the relationship between the numerator and denominator of fractions equivalent to one half to determine if a fraction is less than one half?
If the denominator is more than double the numerator, then the fraction is less than a half.
What is prime factorization in fractions?
You use a factor tree, for the 2 denominators. Yes that is correct the answer on the top but it says 2 denominators. This is the real correct way To do Prime Factorization in fractions first prime factorization the numerator and then the denominator. then put the prime factorization of the numerator on top and put the prime factorization of the denominator on the bottom like fractions.

Where do you use GCF in real life?
When reducing fractions to their simplest form the greatest common factor of their numerator and denominator must be found.
