evaluate and write answer in the lowest terms 9/11-3/11+7/11?

Answer 1

9/11-3/11+7/11=
6/11+7/11=
13/11=1 2/11

Answer 2

9/11-3/11 +7/11 = 13/11 or 1 2/11

To all of you who said that 13/11 cannot be simplied further, think of this:
9 - 3 =6 and 6 + 7 =13
7 -3 =4 and 4 + 9 =13
-3 + 9 = 6 and 6 + 7 =13
9 + 7=16 and 16 -3 = 13
-3 +7 = 4 and 4 + 9 =13


No matter how you add or subtract the numerator, the answer comes out as 13. Had the denominator been 13, the answer would have come out as 13/13 or 1.
In a pie chart, for example, you can NOT have 13 pieces if it is cut for only 11. So, the answer is that 13/11 = 1 2/11 (or 11 times 1 =11 and 11+2=13)

Answer 3

Like everyone previously has answered correctly, the answer is 1 and 2/11. The fractions have the same common denominator, which is 11. It's like in Algebra, when you have 2x+2x, the x is the common variable. Therefore, 9/11-3/11+7/11 would be the same as saying 9x-3x+7x= 13x. Replace the x with the number 11 and you get 13/11. This is a number that needs to be changed to a mixed number, which is 1 and 2/11. This is because you divide 13 by 11. The same applies when you take 10/5. 10 divided by 5 equals 2. Same for 13/11. 11 goes into 13 ONCE with a remainder of 2. Therefore, it is written as a mixed number, 1 and 2/11.

Answer 4

9/11-3/11+7/11
=(9-3+7)/11
=13/11
=1 2/11

Answer 5

1 2/11

Answer 6

1 and 2/11

Answer 7

13/11

Answer 8

13/11

Answer 9

1/2/11

Answer 10

9/11-3/11+7/11= (9-3+7)/11 = 13/11

There's your answer. It can't be simplified.
