How much do you need to add to -6 to make 6?
You need to add 12.
What is 2 over 3 add 1 over 2?
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.
When do you need to find the Least common denominator in a problem?
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.
How do you add dissimilar fractions with mixed number?
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
What do you need to add to -6 to get 17?
17 - (-6) = 23 Therefore, the number you have to add to -6 to make 17 is 23.
Why do fractions need to have a common denominator?
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
How much do you need to add to -6 to make 6?
You need to add 12.
What do you need to add to -9 to get to 6?
You need to add 6 - (-9) = 6 + 9 = 15.
How do you add fractions in simplest form?
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
What is 2 over 3 add 1 over 2?
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.
