What is the unlike denominators for 3-4 plus 7-10?
The denominator of 3/4 is 4 The denominator of 7/10 is 10 4 and 10 are not the same number so the two fractions are said to have unlike denominators.
What is 3 over 4 plus 1 over 8?
3 1 7 4 + 8 is 8. Remember to change the denominators into common denominators. (3/4 would turn into 6/8)
What is 2 over 3 plus 2 over 3?
4 over 3. In adding fractions, you just add the numerators together if the denominators are the same.
What is three over four plus one over six?
You need to convert them to the same denominators. 3 over 4 is 9 over 12 and one over six is two over 12. Adding them together gives 11 over 12.
What is the sum of negative 2 over 7 plus 7 over 9?
The SUM is 31over63. When adding two fractions with uncommon denominators you give them a common denominator by multiplying the denominators. Then multiply the numerators by which their denominator was multiplied. This keeps the problem balanced. You would then have -18over63 plus 49over63. -18 plus 49 equals 31, giving you 31over63. If you needed to divide negative 2 over 7 by 7 over 9, the answer would be -18/49 because you 'keep' the first fraction, 'change' the function to multiplication, and 'flip' the second fraction when dividing fractions.
What is 1 over 2 plus 2 over 5 by adding fractions with unlike denominators?
9 over 10
What is the unlike denominators for 3-4 plus 7-10?
The denominator of 3/4 is 4 The denominator of 7/10 is 10 4 and 10 are not the same number so the two fractions are said to have unlike denominators.
1 over 9 plus 4 over 9?
If you are using the word "over" to describe that these numbers are fractions, then 1/9 plus 4/9 is 5/9. Since the denominators are the same, you simply add the numerators of both fractions, and you have your answer, 5 over 9.
What is three eighths plus one fourth?
The denominators are different, so find the equivalent fractions using the LCD , then add the fractions with the denominators.
What is 3 over 4 plus 1 over 8?
3 1 7 4 + 8 is 8. Remember to change the denominators into common denominators. (3/4 would turn into 6/8)
What is 2 over 3 plus 2 over 3?
4 over 3. In adding fractions, you just add the numerators together if the denominators are the same.
What is 5 over 15 plus 3 over 5 in simplest form?
5/15 + 3/5to add fractions denominators must be the same and 15 will do here using form of 15/15 + 3*3/3*55/15 + 6/15= 11/15================
What is three over four plus one over six?
You need to convert them to the same denominators. 3 over 4 is 9 over 12 and one over six is two over 12. Adding them together gives 11 over 12.
What is the sum or difference of 1 over 4 plus 2over 4?
plus indicates that it is a sum (not a difference): 1/4 + 2/4 = 3/4. You can just add the numerators, since the denominators are the same.
What is 3 over 10 plus 1 over 20?
Before adding the fractions together, it is best to get like-denominators:3/10 + 1/20or6/20 + 1/20 = 7/20
What is the sum of negative 2 over 7 plus 7 over 9?
The SUM is 31over63. When adding two fractions with uncommon denominators you give them a common denominator by multiplying the denominators. Then multiply the numerators by which their denominator was multiplied. This keeps the problem balanced. You would then have -18over63 plus 49over63. -18 plus 49 equals 31, giving you 31over63. If you needed to divide negative 2 over 7 by 7 over 9, the answer would be -18/49 because you 'keep' the first fraction, 'change' the function to multiplication, and 'flip' the second fraction when dividing fractions.
What is one-fifth plus five-eighths if you are adding with unlike denominators?
You have to find the least common denominator of 5 and 8. That's 40. 1/5=8/40 5/8=25/40 Add numerators. Answer=33/40
