To compare fractions which are not similar, the fractions must be made similar by putting them over a common denominator. There are two similar ways of doing this:Find the lowest common multiple of the denominators. Multiply the first numerator by whatever number you multiply the first denominator by to get that multiple, and do the same with the second numerator and denominator. You can then compare the numerators.Multiply the first numerator by the second denominator, and the second numerator by the first denominator, and put both numerators over the product of the two denominators. You can then compare the numerators.
Numerator, Denominator or Denominator, Numerator.
Convert them into equivalent fractions with the same denominator and then compare the numerators.
The same numerator or the same denominator.
There are places where this term is used. 1st- to compare fractions across an equals you are multiplying each side by the product of the denominators. It looks like you multiply the numerator of the left side times the denominator of the right and put that product on the left side. Multiply the numerator of the left times the denominator of the right and put that on the right. In algebra this is good when looking for an unknown. 2nd- when comparing fractions to see which one is bigger you can multiply up from the denominator to the other numerator and compare these numbers to see which one is bigger.
Option 1: Find a common denominator for the two fractions. It need not be the least common denominator; for example, for two fractions, if you just multiply the two denominators, you get a common denominator. Convert all the fractions to the common denominator. Then you can compare. Option 2: Convert each fraction to decimal, by dividing the numerator by the denominator. Then you can compare the decimals.
The smaller fraction has the smaller numerator.
Only Fractions with a Common Denominator can be directly compared.
Change the fractions to the same denominator then compare.A quick way is to multiply UP on cross multiply and compare.
One way to compare two fractions is to convert both to a common denominator. Then the only difference is in the numerator. Comparison of the numerator is then sufficient to compare the fractions. A percentage is equivalent to converting the fractions to a denominator of 100.
To compare if they are the same (ie equivalent fractions), make them both into equivalent fractions with the same denominator and compare the numerators. To find equivalent fractions multiply (or divide) both the numerator and denominator by the same number. → 1/2 = (1×2)/(2×2) = 2/4 → 3/4 = 3/4 The two fractions now have the same denominator (4), so compare their numerators: ½ now has a numerator of 2 whereas ¾ (still ) has a numerator of 3. 2 does not equal 3 so ½ does not equal ¾; ie ½ and ¾ are not equivalent fractions.
The usual method is to convert the fractions to equivalent fractions with a common denominator. Then you can simply compare the numerators. You can also convert each of the fractions to a decimal - this can easily be done with a calculator, simply divide the numerator by the denominator.
If the fractions have different denominators, you need to: 1) Convert to equivalent fractions with a common denominator, 2) Compare the numerators. If the fractions already have the same denominator, there is no need for the first step - which happens to be the most difficult step. Note that as a shortcut, you don't need the LEAST common denominator, any denominator can do. Thus, you can just use the product of the two denominators as the common denominator. As a result, to compare the fractions, you simply multiply the numerator of each fraction by the denominator of the other one, and then compare. However, this is still more work than simply comparing two numbers.
1) You can convert to a proper fraction with a larger numerator (top number) than denominator (bottom number) then multiply to give you the same denominator. or 2) convert to a decimal number by dividing the numerator by the denominator or 3) covert to a percentage by doing the above and then multiply by 100.
You can either convert fractions to decimals and compare the decimal numbers; find equivalent fractions with the same denominator and then compare numerators or find equivalent fractions with the same numerator and then compare 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.
You DO need a common denominator to add, subtract, or compare fractions. You DO NOT need a common denominator to multiply or divide fractions.
To compare two fractions, you convert them to equivalent fractions with the same denominator. Then you can compare their numerators (top parts). In that case, the fraction with the larger numerator is larger.
To compare two fractions, convert them to a common denominator.To compare two fractions, convert them to a common denominator.To compare two fractions, convert them to a common denominator.To compare two fractions, convert them to a common denominator.
Put them next to each other and see which one is larger.
To compare fractions, convert them to a common denominator - in this case, a denominator of 8 will work.To compare fractions, convert them to a common denominator - in this case, a denominator of 8 will work.To compare fractions, convert them to a common denominator - in this case, a denominator of 8 will work.To compare fractions, convert them to a common denominator - in this case, a denominator of 8 will work.
if they have the same denominator, you just look at the numerator and if your seeing which one's bigger, then the one with the bigger numerator is obviously bigger.
If the denominators are the same, the one with the greater numerator is greater.
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.
You cannot compare fractions by using the GCF since GCF determines the common factors of both fractions. Instead, use the LCD to compare the fractions. Find the LCM of the denominator terms of the fractions. Then, obtain the fractions with the common denominators. Finally, compare the numerator values to determine which fraction is the greatest/least.
