Use the additive inverse to find −1223−(−856). Write the answer as a mixed number.(1 point)
That’s wrong
-12 2/3-(-8 5/6)=
what is −12 2/3 − (−8 5/6) as a mixed number
To find the sum of −1223 and the additive inverse of −856, we need to change the sign of −856.
The additive inverse of −856 is 856.
Now, we can find the sum of −1223 and 856:
-1223 + 856 = -367
Therefore, −1223 − (−856) = -367.
To write the answer as a mixed number, we divide the absolute value of -367 (367) by the denominator of the fraction (-1) and write the fraction in its simplest form.
367 ÷ 1 = 367
Therefore, −1223−(−856) as a mixed number is -367.
To find the sum of -1223 and the additive inverse of -856, we first need to find the additive inverse of -856.
The additive inverse of any number, denoted by (-n), is the number that when added to the original number will result in zero. In other words, the additive inverse of -n is the number that, when added to -n, gives 0 as the result.
To find the additive inverse of -856, we need to find the number that, when added to -856, equals 0.
-856 + x = 0
To simplify, we can solve for x:
x = -(-856) (to remove the negative sign, we multiply by -1)
x = 856
Therefore, the additive inverse of -856 is 856.
Now that we have the additive inverse of -856, we can find the sum of -1223 and 856:
-1223 + 856 = -367
The result is -367. To write it as a mixed number, we need to express it as a whole number plus a fraction.
Since -367 is negative, we can express it as -367/1, which is equivalent to (-367).
Therefore, the answer, written as a mixed number, is (-367).
To find the additive inverse of a number, we change the sign of the number.
The additive inverse of -856 is 856.
Now we can subtract -856 from -1223:
-1223 - (-856) = -1223 + 856
To add these two numbers, we align them vertically and add the corresponding place values:
```
-1223
+ 856
-------
```
Starting from the rightmost column, we have:
3 + 6 = 9
2 + 5 = 7
2 + 8 = 10
Write down the 0 and carry over the 1:
1 + 1 = 2
Adding all the column values, we have:
```
-1223
+ 856
-------
367
```
Therefore, -1223 - (-856) = 367.
The answer as a mixed number is: 367
