Question

THANK YOU

Answer 1

7/9 - (-13/18)
= 7/9 + 13/18
= 14/18 + 13/18
= 27/18
= 3/2

Answer 2

*Eliminate parenthesis - use the Distribution Method. Distribute the negative sign with the negative sign in parenthesis.

7/9 + 13/18

7/9 = x/1 + 13/18= x/1

First: find the least common denominator which is, 18.

7/9 = x/18 + 13/18= x/18

Sec: multiply the denominators & corresponding numerators with the missing terms to get 18.

(7/9)(2) = x/18 + (13/18)(1) = x/18

(7/9)(2) = 14/18 + (13/18)(1) = 13/18

Third: combine the fractions with the same denominator.

14/18 + 13/18

27/18

Simplify the fraction into lowest terms.

27/18 = 3/2

Answer 3

The lowest common denominator is 18, since 2*9=18. So multiply numerator and denominator of 7/9 to yeild (7/9)(2/2)=14/18 and rewrite the problem (14/18)-(-13/18). Since subtracting a negative quantity is the same as adding that same positive quantity (i.e., since -1(-1)=1), the answer is
(14/18)+(13/18)=27/18=1.5.

Answer 4

You're actually subtracting a negative number; so you are really adding.

First, get a common denominator (which is 18 in this case) by multiplying the first figure by 2/2:
14/18 + 13/18 = 27/18

Then simplify by dividing the numerator and denominator by 9:
3/2 or 1 1/2

Answer 5

14/18 - (-13/18) = 27/18 =1 1/2

Answer 6

7/9 = 14/18

so 14/18 -(-13/18) = (14+13)/18 = 27/18= 3/2

Answer 7

First you divid 7 by 9. Then you add to it 13 divided by 18.

General rules... first you perform the mutliplications and divisions then you perform the additions and the subtractions.

Subtracting a negative is just adding.
