You need to add 12.
7/6 or 1 1/6 If you want to add 2/3 and 1/2 you first need to find a common denominator. In this case, 6 is the least common denominator. Then you rewrite the fractions with the new denominator. 2/3=4/6 and 1/2=3/6. Now you can add them. 4/6+3/6=7/6 and 7/6 is the same as 1 and 1/6.
Least common denominators or LCDs are very important when adding fractions.For example, if we want to add 1/2 and 1/3 we need to make them look the same. That is to say we can only add like things. So we find the LCD which is 6 in this case. 1/2 is 3/6 and 1/3 is 2/6. Now we can add these and we have 5/6.Without the LCD we could not add these or many other fractions.We extend this idea when we add rational expressions.
You can add the whole part of the numbers separately - no need to convert those. Then add the fractional parts in the usual way, i.e., find a common denominator, convert the fractions to this denominator, and add the numerators. Here is an example: 5 1/2 + 3 2/3 Add the whole part and the fractional part separately: 8 + (1/2 + 2/3) Convert to a common denominator: 8 + (3/6 + 4/6) Add the fractional part: 8 7/6 Since in this case 7/6 is greater than 1, you need to subtract one, and add one to the whole part: 7 1/6
17 - (-6) = 23 Therefore, the number you have to add to -6 to make 17 is 23.
They need a common denominator when you add them. For example, if you want to add 1/2 and 1/3, you need to change the fractions to equivalents that share the same denominator, so you can combine them. 1/2 + 1/3 = 3/6 + 2/6 = 5/6
You need to add 12.
You need to add 6 - (-9) = 6 + 9 = 15.
Fractions will need to have the same denominator to add the numerator then reduce the answer as needed to simplest forms. 1/2 + 1/3=3/6 + 2/6=5/6
7/6 or 1 1/6 If you want to add 2/3 and 1/2 you first need to find a common denominator. In this case, 6 is the least common denominator. Then you rewrite the fractions with the new denominator. 2/3=4/6 and 1/2=3/6. Now you can add them. 4/6+3/6=7/6 and 7/6 is the same as 1 and 1/6.
