You need to change the denominators so they are the same ( by timesing them together) E.g. 1/7 1/2 7x2=14

How are adding fractions different?

When adding or subtracting fractions their denominators must be the same


How do you minnous fractions?

Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

How is adding like fractions and adding unlike fractions the same?

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.


Why does the equivalent fraction make adding and subtracting fractions easier?

You cannot add or subtract fractions with different denominators. If the denominators are different then you need to work with equivalent fractions.


Can you multiply fractions that have a different demonminator?

Yes. When multiplying and dividing fractions your denominators do not have to be the same. The denominators only haveto be the same if you are subtracting or adding them.


What are the rules for adding fractions?

Ensure that the denominators are the same when adding or subtracting fractions.


how to rename fractions using LCM?

When adding or subtracting fractions with different denominators their lowest common denominator must be found first by using the LCM of their denominators


Are the steps for like and unlike denominators the same or different?

It depends what you are doing with the fractions. If you are multiplying or dividing fraction, the denominators do not need to be the same and the calculation can be carried out immediately. If you are adding or subtracting fractions, the denominators must be the same; if you have different denominators, the fractions must first be changed into equivalent fractions with the same denominator. When the denominators are the same (or have been made the same as equivalent fractions from being different) the calculation can be carried out.


When will you need to find the multiples and factors?

When adding or subtracting fractions with different denominators and when reducing fractions to their lowest terms


Why do you have to have a common denominator?

A common denominator is needed when adding or subtracting fractions of different denominators.


What is disimiliar fraction?

Dissimilar fractions have different denominators.


How do you subtract improper fractions with different denominators?

It's the same thing as adding or subtracting normal fractions - just make sure both fractions have the same denominators (by either multiplying the denominators or simplifying the fraction - whichever the question needs).
