−1/1/3+(−423)=
To add -1/1/3 and -423, we need to convert -1/1/3 into a mixed number.
1/1/3 = 1 + 1/3
Now we can add:
-1/1/3 + (-423) = -1 + 1/3 + (-423)
To add the whole numbers, we can rewrite -1 as -3/3:
-3/3 + 1/3 + (-423) = -3/3 + 1/3 + (-423)
Now we have a common denominator of 3:
-3/3 + 1/3 + (-423) = -3/3 + 1/3 + (-423) = -2/3 + (-423)
Now we add the fractions:
-2/3 + (-423) = (-2 - 423) / 3 = -425/3
Therefore, -1/1/3 + (-423) = -425/3.
