How do you add fractions with different denominators? Thanks if you help :)
You must either
change the fractions to equivalent fractions with a common denominator
or
change the factions to equivalent decimals.
In google type :
add fractions with different denominators
You wil find many, many sites.
can't do it. Fractions with different denominators are different animals. Think of the denominator as a unit. A half is not the same as a third, just as apples are not oranges.
So, in order to add them, you need to convert them into the same units. To add 2/3 + 1/2, you have to make them somehow the same kind of thing.
If you cut a pie into 6 pieces, two of those pieces make 1/3, and 3 of them make 1/2. So, to do the addition, change things up so that
2/3 + 1/2
= 4/6 + 3/6
Now everything is the same kind of object: sixths
Now you can add them up
4/6+3/6 = 7/6 = 1 1/6
So, learn about something called the Lowest Common Denominator. To add fractions with different denominators, convert them so they are all multiples of the LCD. Then they can be added.
2/7 + 3/5 + 1/3
= 30/105 + 63/105 + 35/105
= 128/105
Don't think about to much to much baby
Adding fractions is simple I will have this as a blog
To add fractions with different denominators, you need to find a common denominator for the fractions. Here's a step-by-step explanation of how to do it:
1. Identify the denominators of the fractions you want to add.
2. Determine the least common multiple (LCM) of the denominators. The LCM is the smallest number that is evenly divisible by both denominators. For example, let's say you have the fractions 1/4 and 1/5. The LCM of 4 and 5 is 20.
3. Find equivalent fractions for each fraction with the common denominator. To do this, multiply the numerator and denominator of each fraction by the same number that turns their original denominators into the LCM. Using the previous example, multiply 1/4 by 5/5 and 1/5 by 4/4. This gives you 5/20 and 4/20, respectively.
4. Add the fractions together. Since they now have the same denominator, you can simply add the numerators together while keeping the denominator the same. In our example, 5/20 + 4/20 equals 9/20.
So, when adding fractions with different denominators, the key is to find a common denominator and then convert each fraction to an equivalent fraction with that denominator. Afterward, it's just a matter of adding the numerators together.
