Is it always necessary to find the least common denominator to compare the sizes of fractions?
It is not always necessary to find the least common denominator to compare the sizes of fractions. When comparing fractions with the same denominator, you can simply compare the numerators. If the denominators are different, you can find a common denominator by multiplying the denominators together, but it is not always required for comparison. Alternatively, you can convert the fractions to decimals for easier comparison in some cases.

How to add fractions having similar numerators but different denominators?
The first step, to add, subtract, or compare fractions, is always to convert the fractions to equivalent fractions, that all have the same denominator. You can use one of several techniques to get the LEAST common denominator, or simply multiply the two denominators to get a common denominator (which in this case may, or may not, be the smallest common denominator).
Is four sevenths the same as two fifths?
To compare two fractions, find a common denominator (multiplying the two denominators will always give you a common denominator), convert both fractions to the common denominator, then compare. Another - actually easier - way to compare two fractions is to convert both to decimal. Just pick up a calculator, and divide the numerator by the denominator.
What is a unit rate where the the denominator is one unit?
its always going to be in the denominator of 2 fractions.
What is always needed when adding and subtracting fractions?
a common denominator
When adding fractions what you always must do is find the?
Common denominator

What fractions will equal to 1?
Fractions will always equal 1 when their numerator is the same as their denominator

a common denominator
When adding fractions what you always must do is find the?
Common denominator
Is the least common denominator of two fraction is always greater than the denominator of the fractions?
Not always. If one denominator is a multiple of the other, the LCD will be the larger one.
What is the simalarites betweenproer and improper fractions?
Both proper and improper fractions have a numerator and a denominator. In a proper fraction the numerator is always less than the denominator. In an improper function the numerator is greater than the denominator
What is true about the numerators of two like fractions with a sum of 1?
That their sum is always equal to the denominator.
What is the common denominator for 9 and 13?
The common denominator for 9 and 13 is the product of the two numbers, which is 9 * 13 = 117. In fractions, the denominator represents the total number of equal parts into which a whole is divided. When adding or subtracting fractions, it is necessary to have a common denominator to combine the fractions accurately.
Is the product of two denominators always a common denominator?
Only if you have just two fractions.
