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).
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.
its always going to be in the denominator of 2 fractions.
Fractions will always equal 1 when their numerator is the same as their denominator
a common denominator
Not always. If one denominator is a multiple of the other, the LCD will be the larger one.
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
That their sum is always equal to the denominator.
Only if you have just two fractions.
Its probably easier if you see percentage as a fraction (always with a denominator of 100) this puts it in the same area as other commonly used fractions such as one half, one quarter etc.
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
A fraction has the numerator on 'top' and the denominator on the 'bottom'. If the two fractions have the same denominator (eg: 1/4 and 3/4) then you can simply compare the numerators, and the larger fraction has the larger denominator (in the above example, 3 is bigger than 1 so 3/4 is bigger than 1/4.) If the Denominators are different then you must find the common denominator. Do this by 'adjusting' (multiplying numerator and denominator by the same number) either one or both fractions, then comparing the numerators. eg: 2/3 and 1/2. The denominators are different, and the common denominator would be 6 (2x3). (This is not always the smallest though, like the lowest common denominator for 1/4 and 1/6 is 12, not 24.) Once you have the lowest common denominator, adjust the fractions: 2/3 becomes 4/6 (as you had to multiply 3 by 2 to get 6, multiply the numerator by 2). 1/2 becomes 3/6 (again, multiply numerator by the same number as the denominator). Compare the fractions: we have 3/6 and 4/6. 4/6 is bigger, which is the same as 2/3, therefore 2/3 is bigger than 1/2.
5/10 is equal to 1/2. Whatever you multiply the numerator by you must multiply the denominator and you will always get same valued fractions
Controlled variables are always necessary in an experiment. This is because a baseline is needed to compare the results to.
No. Only if you're adding or subtracting and then only if the denominators are different.
there are 3 types of fractions proper,improper,mixed proper fractions:-numerator is less than denominator like-2/3,5/7,6/9 improper fractions:- numerator is greater than denominator like-3/2,5/4,9/7 mixed fractions:-always improper fractions are converted to mixed fractions,mixed fractions are combination of proper fractions and whole numbers like-2.2/7,5.3/7
When converting fractions to equivalent fractions, it must be remembered that you always multiply the numerator and denominator by the same amount. In this case, the denominator is 2 and we want it to be 6. Therefore we have to multiply top and bottom of the fraction by 3. Do this and we get 3/6. Thus the fraction equal to 1/2 with a denominator of 6 is 3/6.
Technically, the answer is always "No", simply because there's no such thing asan "interger".However, a fraction is equivalent to an integer if its numerator is a multiple ofits denominator.
There is always an LCD for a set of fractions, even if it's only the product of the denominators.
It is not always helpful.Some people may find it helpful when comparing fractions. By converting them into percentages they are made into like fractions: all with the denominator 100.
It is not always necessary. For example 100/5 = 20. No decimal points in sight!
A percent is a fraction that always has 100 as the denominator (bottom number). So 14% is 14/100 or 0.14.
I learned to always change the denominators before adding or subtracting the numerators. You must always have a common denominator before adding or subtracting.
