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 subtract fractions with like denominators, subtract the numerators , and write the difference over the denominator. Example : Find 45−25 . Since the denominators are the same, subtract the numerators.

The same way as proper fractions. Make sure the denominators are the same. If they're not, convert them to equivalent fractions with similar denominators. Then you can see which numerator is greater.

If the denominators are the same (which is what I understand by "similar fractions"), just subtract the numerators (the upper part).

As a review, similar fractions (also like fractions) are fractions having the same denominators

Similar fractions are those denominators the same.

You can compare similar fractions by looking at their numerators. You can compare dissimilar fractions by converting them to similar fractions and looking at their numerators. You can convert a dissimilar fraction to a similar fraction by finding the least common denominator.

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.

If the denominators are the same, just add or subtract the numerators. For example, 2/7 + 3/7 = 5/7. am i right?

When their denominators are the same or different numbers.

To multiply two fractions, multiply the numerators together, then the denominators, then put the new numerator over the new denominator. Simplify if you can. To divide fractions, invert the second fraction and multiply as just described.

Their denominators. If they are the same, the fractions are similar. If they are not the same, the fractions are dissimilar.

Just add the numerators and copy the denominator.

To add similar fractions such as 3/8 and 4/8 you simply add the numerators (top numbers) and keep the denominators(the bottom numbers) the same. so 3/8 + 4/8=7/8

I assume you mean, with different denominators. If you want to add the fractions, subtract them, or compare them (determine which one is greater), you have to convert them to similar fractions (fractions with the same denominator) first. Converting to similar fractions is not necessary, and usually doesn't even help, if you want to multiply or divide fractions.

To multiply two fractions, whether or not they are similar, the numerator of the answer is the product of the two numerators. The denominator of the answer is the product of the two denominators.So (a/b)*(c/d) = (a*c)/(b*d).

Two ways: convert them to decimals or convert them to similar fractions and compare the numerators.

similar fraction is the same denominator and dissimilar fraction is cannot the same denominators

Adding similar fractions is easy, but adding dissimilar ones requires an additional step. Before you begin, you must know a few important key terms. First, the number on the top of a fraction is called the numerator, while the number on the bottom of a fraction is called the denominator. Similar fractions have the same denominator, also called a common denominator. To add dissimilar fractions (fractions with different denominators), you must first convert the fractions so that the denominators are the same.

Just subtract the numerators and copy the denominator

For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.

Equivalent fractions have the same value. 3/4 is equivalent to 6/8 Similar fractions have the same denominator. 3/5 is similar to 4/5 Dissimilar fractions have different denominators. 4/7 is dissimilar to 11/16

Similar fractions occurs when the denominator or the bottom numbers are the same. In this case, adding similar fractions requires you to add the numerators; the top numbers together, and to keep the denominator the same. An example would be to add 2/8 and 5/8 equals 7/8.

Two ways: Convert them to decimals and compare or convert them to equivalent fractions with a common denominator and compare the numerators.

Disimilar fraction.are fraction with different denominators. Similar fraction.are fraction with the same denominators.

The instructions are quite simple, but this is for similar denominators: 1. Line them up. 2. Add the numerators. 3. Put your sum over the same denominator as the other fractions. 4. *ONLY IF THE NUMERATOR IS LARGER THEN THE DENOMINATOR* Turn the improper fraction into a mixed number. However, if the problem states it wants it as an improper fraction, which normally it won't, leave it as it is.
