Hi,

7/8 - n - 9/9 + 13/7 =

7/8 - n - 1 + 13/7 =

Get a common denominator of 56 for all numbers.

49//56 - n - 56/56 + 104/56 =

97/56 - n <== ANSWER

Second Solution if you want a common denominator for everything:

7/8 - n - 9/9 + 13/7 =

7/8 - n - 1 + 13/7 =

Get a common denominator of 56 for all terms.

49//56 - 56n/56 - 56/56 + 104/56 =

97 - 56n

------------ <== ANSWER with common denominator

....56

I hope that helps!! :-)

Answer 2

-n= -7/8+9/9-13/7

n= 7/8-1+13/7

n= 100/56 = 25/14

Answer 3

I assume you wanted to solve

7/8 - [(n-9)/9] + 13/7

now make the denominator equal

[(7X9X7)/(8X9X7)] - [{(n-9)X8X7}/(9X7X8)] +[(13X9X8)/(7X8X9)]

= [441/(7X8X9)] - [(56n - 504)/(7X8X9)] + [936/(7X8X9)]

= [(441 - 56n + 504 +936)/(7X8X9)]

= (1881 - 56n )/ 504

= (1881/504) - (n/9)

Hope this come to your help :))
