Your equation is the following:
11 7/7 - (-8 3/7)
the first step to solving this is to know that when there is a
"-" sign in front of the parenthesis, you need to change the sign of each term in the parenthesis.
11 7/7 + 8 3/7
now, add the whole numbers and the fractional parts of the mixed numbers separately.
(11 + 8) + (

)
add the whole numbers together
19 + (

)
now add the fractions together
19 + 10/7
next, convert the improper fraction to a mixed number
19 + 1 3/7
now, you will write the mixed number as a sum of the whole number and its fractional part.
19 + 1 + 3/7
add the numbers together
20 + 3/7
finally, write the sum of the whole number and the fraction as a mixed number
20

D is your correct answer, the more trials you do, the closer you get to
an accurate probability. Think of it like scientific trials. The less
you do, the further you are from creating an accurate law of science,
but something that has been tested over and over again is more likely to
be accepted as an accurate fact.
