How do you change a fraction so they have the same denominator?
First, find a common denominator for the two (or more) fractions. Then, for each fraction, multiply numerator and denominator by the same number (different numbers for different fractions, though), to convert to the common denominator.
What is the greatest common denominator of 8 and 96?
the answer is 8 because 8x12=96 and there is no more common denominator of 8 and 96 above 8 so the answer is 8
Why does the fraction that results from adding or subtracting fractions with unlike denominators have a different denominator?
When you add fractions that have unlike denominators, the first step is to convert them so they are expressed as fractions using the least common denominator. The result is that the answer will have a different denominator, or it may use one of the original two denominators.For example if you are adding 1/10 and 3/5, the least common denominator is 10, the problem is rewritten as 1/10 + 6/10 = 7/10But if you are adding 1/5 and 1/6, the least common denominator is 30 and the problem is rewritten as 6/30 + 5/30 = 11/30
What is the common denominator for 1 over 3 and 4 over 9?
Well, darling, the common denominator for 1/3 and 4/9 is 9. You see, to add or subtract fractions, you need a common denominator, and in this case, multiplying 3 by 3 gives you 9. So, there you have it, simple math for a simple question.
What is 11 over 12 minus 3 over 8?
Well, let's take a moment to appreciate the beauty of these fractions. To subtract them, we need a common denominator. In this case, it's 24. So, 11/12 becomes 22/24, and 3/8 becomes 9/24. Subtracted, they give us 13/24, a lovely little fraction full of possibilities.
How do you rewrite a fraction so it can have the same common denominator?
When adding or subtracting fractions with different denominators, changing the denominators so that they have a common denominator is a simple process. Example: 1/3 + 1/8 What you want to do first is multiply 3 by 8, 3*8=24. This will be your common denominator. Next multiply 1/3 by 8/8 so that your answer will have 24 as the denominator. 1/3*8/8=8/24 Now repeat this process with 1/8 by multiplying it by 3/3 to get your 24 denominator. 1/8*3/3=3/24 Now you have both fractions with the same common denominator, all that is left is to add. 8/24+3/24=11/24 And there is your answer.
What is the common denominator for 5 7 9 11?
these are all prime numbers so if they are denominators, the least common denominator would be their product. 5x7x9x11 = 3465
What Is 5 over 6 - 3 over 8?
11 over 24 (11/24) Here's how: You need to find a common denominator. The lowest common denominator is 24, but you can use any common denominator to subtract. So convert 5/6 to 24ths: multiply numerator and denominator by 4 = 20/24, then multiply numerator and denominator of 3/8 by 3 = 9/24. Now subtract 9 from 20 = 11, which is the numerator of the difference: 11/24. This is already in simplest form.
How you could use common denominators to rewrite two ratios to compare them?
Two ratios comprise four numbers - one numerator and one denominator for each ratio. Most people do not find it easy to make comparisons involving four elements.Now, if you use a common denominator, then the ratio with the smaller numerator is the smaller number. Only two numbers - the two numerators - to be compared.Incidentally, you could use common numerators instead, but then the ratio with the smaller denominator would be the bigger number. Some of us do use this, particularly when the numerator is 1. eg 13>11 so 1/13 < 1/11.
What common denominator can 9 11 and 10 go into?
990 is one possible answer.What common denominator can 9 11 and 10 go into? In Math and Arithmetic
What is the common denominator of 9 11 and 45?
The common denominator of any two or more whole numbers, such as 9 11 and 45, 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 is the common denominator of 9 11 and 4?
The common denominator of any two or more whole numbers, such as 9 11 and 4, 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 is the common denominator of 3 9 and 11?
The common denominator of any two or more whole numbers, such as 3 9 and 11, 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 is the lowest common denominator of 11 20?
The lowest common denominator of any two or more whole numbers, such as 11 and 20, 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.
How do you rewrite 5 over 8 and 7 over 10 with the least common denominator?
Well, honey, to rewrite 5/8 and 7/10 with the least common denominator, you first need to find the least common multiple of 8 and 10, which is 40. Then, you can rewrite 5/8 as 25/40 and 7/10 as 28/40. Voila! Now you have them both with the same denominator, making it easier to compare those sassy fractions.
How do you find equivalent expressions that have a lcd?
To find equivalent expressions with a least common denominator (LCD), first identify the denominators of the given expressions. Factor each denominator to find the least common multiple, which will serve as the LCD. Next, rewrite each expression so that its denominator matches the LCD by multiplying the numerator and denominator by the necessary factors. Finally, simplify the resulting expressions if needed, ensuring they remain equivalent to the original expressions.
What is the least common denominator of 3 5 6?
Sir/Ma'am, denominator are fractions, so the is no common denominator. But the least common multiples is 30
