No. Sometimes it is the same as one of them.

If you are allowed to simplify the fractions first, you might even get a smaller number, but I'm not sure what your math teacher is going for in your case.

Is the product of two denominators always a common denominator?

Only if you have just two fractions.

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).

Do you always have to find common denominator when working with fractions?

No. Only if you're adding or subtracting and then only if the denominators are different.

What I there is isn't a lowest common denominator for a fraction?

There is always an LCD for a set of fractions, even if it's only the product of the denominators.

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.

Why is the recipical of A fraction less than one is always a fraction greater than one?

Fractions that are less than one are known as proper fractions. Their denominators are greater than their numerators. Their reciprocals would have numerators greater than their denominators, making them improper. Improper fractions are greater than one.

If two fraction have unlike denominators then the LTD is the product of their denominations?

Answer: I assume you are talking about the least common denominator. If you multiply the denominators, you will get a common denominator. This will always work, if you need to add, subtract, or compare fractions. However, the common denominator you thus get will not always be the LEAST common denominator. Examples: * For denominators 7 and 11, the least common denominator is, indeed, the product (77). * For denominators 4 and 6, the product is 24, but the least common denominator is 12. * The difference can be more extreme, too; for denominators 100 and 200, the product is 20,000, but the least common denominator is only 200. * Or even more extreme: if both fractions have the denominator 551, the product is 303,601. The least common denominator, of course, is just 551. Answer: I am not sure but it's Lcd

What is the greater common denominator for 13 and 41?

The greater common denominator of any two or more whole numbers, such as 13 and 41, will always be one (1) because 'common denominator' refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.

What did you learn from adding and subtracting fractions?

I learned to always change the denominators before adding or subtracting the numerators. You must always have a common denominator before adding or subtracting.

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

Fractions Have The Same Denominators?

Not always but they need to have the same denominators when adding or subtracting them.

What is the common denominator for 143 and 208?

The common denominator of any two or more whole numbers will always be one (1) because common denominators refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers would have to be converted to their fraction equivalents, e.g., x/1, which will always yield a denominator of 1.
