The simplest fraction is 31/273127 or an improper fraction 1 4/27427

Explanation:

To add fractions, first we need to make sure the denominators are equal, and then we can simply add the numerators.

We can use a multiple of the denominators as a common denominator and we can find it by multiplying the denominators with each other.

12*9=81129=81

"1(9)"/81 +"7(12)"/811(9)81+7(12)81

81 is our common denominator and we can modify the numerators by multiplying them with the denominator of the other fraction.

1*9=919=9 and 7*12=84712=84

This gives us "9+84"/81=93/819+8481=9381

This can be further simplified by dividing both the numerator and denominator by 3, which leaves us with "93/3"/"81/3"="31/2793/381/3=3127 as our final answer.

To express this as an improper fraction, we can use long division and divide 31 with 27 and get a quotient of 1 and a remainder of 4. We can express this in an improper fraction 1 4/27427
